Cannot change Chord Symbol durations settings from default on STYLE PAGE

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

Musecore 4.7.4 on OS Ubuntu 24.04.4 LTS downloaded from https://musescore.org/en/download/musescore-x86_64.AppImage
Result: MuseScore-Studio-4.7.4.260706075-x86_64.AppImage

1. Create a guitar line using slashes to create various rhythm and note/chord durations including rests.
2. Above the slashes add chord symbols.
3. Play the test line.
   RESULT: All chords sustain until the next chord. (DEFAULT BEHAVIOR.)

CASE:
I want the chord durations to match the slash notations including rests.

5. Right click on a chord symbol and select STYLE.
6. Style page displays.
7. Scroll to bottom and in the section PLAYBACK attempt to change the default behavior from "Until Next Chord Symbol" to "Chord/Rest Duration."
   RESULT: No attempts at clicking the desired third selection at the bottom will change the option list selection.
8. Click OK.
9. Play the test line again to verify behavior has not changed.
10. Test the other option lists on the style page.
    RESULT: No option lists can be changed from default.
    SEE CLOUD URL RECORDING of FAILED UI INTERACTIONS.

Attempted Solution.
On the same Styles page I clicked Reset All Styles to default. RESULT = No Change
At main menu Help Revert to Factory. RESULT = No Change

Other Diagnostics:
Launched Audacity and the EDIT SETTINGS screen which also has option drop down list widgets and they worked correctly.

Regression

I was unable to check

Operating system

Ubuntu 24.04.4 LTS

Additional context

Running MuseScore AppImage as executable "Run as Program." For many past versions and current version no attempted procedure (many tried) will "install" the appimage. NOTE: Exept for this UI feature all other features of the program I use appear to function without any known issues.

Checklist

• This report follows the guidelines for reporting bugs and issues
• I have verified that this issue has not been logged before, by searching the issue tracker for similar issues
• I have attached all requested files and information to this report
• I have attempted to identify the root problem as concisely as possible, and have used minimal reproducible examples where possible

Start by reproducing the issue from the Style page's Playback section using the reported slash-and-chord example, then inspect how the style option lists handle selection. Done means the options can be changed and saved, and playback reflects the selected chord or rest duration rather than the default.
