Many Final Cut Pro users have recently been running into a very frustrating bug where text styles like Bold, Semibold, Bold Italic, or Oblique appear correctly inside the Viewer, but revert back to Regular after rendering or exporting the project.
The issue has been reported by users on different Mac models, different versions of Final Cut Pro, and with both built-in and third-party title templates. Some editors say it started after updating to newer versions of macOS, while others noticed it after updating the Final Cut Pro itself. Either way, the problem seems very real, annoying and surprisingly widespread right now.
The good news is that there are several workarounds that can help until Apple properly fixes it.
The issue:
- You select a title in Final Cut Pro.
- You change the font style from Regular to Bold or Bold Italic.
- The Viewer updates correctly and shows the text as bold.
- But the Text Inspector still acts strangely or keeps “Regular” internally.
- When exporting or rendering, the final video reverts back to Regular text.
How to Fix (workarounds):
1. Change Another Text Inspector Parameter
This is the workaround that worked for me. After selecting Bold or another font style:
- Change another setting temporarily.
- Then change it back.
For example:
- Align text to Right > back to Center
- Increase size slightly > revert it
- Adjust the tracking > reset it
2. Type a Character Then Delete It
Another surprisingly effective fix that worked for me. After changing the font weight:
- Click into the title text
- Type a random letter
- Delete it immediately
Several editors said this “forces” Final Cut Pro to save the style change properly before export.
I know it sounds silly, but it actually makes sense if the bug involves a inspector refresh behavior.
3. Save and Reapply a Text Style Preset
Some users fixed the problem by:
- Configuring the title exactly how they want
- Saving the text format/style preset
- Reapplying that preset to titles
This seems to bypass the inspector bug in some projects.
4. Delete Render Files
Sometimes old render files may continue caching the incorrect style. Try this:
- Select your Library or Project
- Go to:
- File > Delete Generated Library Files
- Delete:
- Render Files
- Optimized Media (optional)
Then let Final Cut Pro re-render everything again.
Some users reported partial success with this method.
5. Validate Fonts in Font Book
Even though this usually is not the main cause, it’s still worth checking.
Open:
- Font Book, you can use Spotlight to open it.
Then:
- Select the affected font
- Run validation
- Look for duplicate or corrupted versions
Duplicate .ttf and .otf installations of the same font may confuse Final Cut Pro in certain situations.
6. Avoid Copy/Pasting Old Titles
Some users have reported that copied titles may inherit broken formatting behavior.
Instead of duplicating old titles repeatedly:
- Create a fresh title directly from the Titles Browser
- Reapply the formatting manually
Not ideal, but sometimes cleaner.
7. Test in a New Library
Sometimes the issue behaves differently in fresh libraries. Here’s what to do:
- Creating a brand new library
- Adding a basic title
- Testing export immediately
If the problem disappears there, your original library may contain corrupted cache or template state data.
Fixes that do not help
You may try the following but these do not help with this issue:
- Reinstalling Final Cut Pro
- Resetting preferences
- Rebooting macOS
- Using different fonts
- Switching between built-in and third-party titles

Having that issue and hoping it’s fixed soon. My work around was to delete the fonts in font book that I don’t need and then export in FCP only with that font. Not great but it works.
