phpstorm strange behavior lately with 'undo Reload from Disk' and saves

Within the past 2 weeks I have had 2 strange issues come up repeatedly throughout the workday.

1. the number of ‘undo’s is dramatically lower; sometimes just 1 or 2 undos and then I get a dialog asking if i want to ‘Undo Reload from Disk’. On a file that I've had opened and been working on for a long time.

2. I save often, but in the past 2 weeks I sometimes get a popup when I save that says something like "Do you want to keep memory changes or load disk changes' or similar. 

Both of these started in the past 2 weeks. 

phpStorm version 2026.3 build #PS-263.7307.215

MacOS 27.2.1
