Mint 22 & Mintupdate 6.1.5 Not Permitting Ignore Current Update

No source files or tests are named. Start by reproducing the issue with the reported Mint 22 and mintupdate 6.1.5 steps, then trace the handling of “Ignore the current update for this package” using the supplied logs. Done means the selected LibreOffice update is removed from the list and remains excluded after refresh.

Describe the bug
I am running Mint 22 Cinnamon with the 6.8 kernel.
Mintupdate 6.1.5 does not permit Ignore Current Update to function. I selected to prevent a LibreOffice update from occurring but it is not removed from the list of updates (as it did in Mint 21.3). Incidentally, this update causes my LibreOffice installation to be completely broken. I had to use TimeShift to fix the problem.

Screenshots

To Reproduce
Steps to reproduce the behavior:

1. Right-click the update name
2. Click on 'Ignore the current update for this package'

Expected behavior
I expect the update to be removed from the list of updates so that it is not included with the rest of the updates.

Distribution:

• Linux Mint 22
• LMDE: Cinnamon 6.2.7
• Kernel: 6.8.0-40

Software version:
