Command Z is taking me to way older iterations

Hey there!
Downloaded Glyphs 4 and noticed that when I hit Command + Z to undo my last action it’s going back to a version many actions ago. It’s been doing this for a couple weeks now. Anyone else also experiencing this glitch?

Do you have plugins installed?

Yes, I have these plugins installed.
I also had these 2 installed, but I just now removed them since I don’t use them: Show Stems (Light) and Show Distance & Angle (by Mark2Mark)

Can you try to start without plugins. Hold down the Option + Shift key when you start Glyphs.

Was waiting to respond till I could really test and see if issue came back. That seems to have fixed the issue! Thanks for the quick help.

Then it seems that a plugin is causing the undo issue.
Please disable the first half of all plugins and check if the problem persists. If the issue remains, the problematic plugin is likely still active. If the issue is resolved, re-enable the first half and disable the other half.
Repeat this process, progressively narrowing down your selection, until you identify the specific plugin or plugins causing the issue.
