Plugin still active after uninstalling plugin, it is moving newly-created UI

[hipenguinflip (Hipen)]

Reproduction Steps

Only happens in Untitled Game - Roblox, not in new place files. Seems to be caused by the AutoScale Plus - Roblox plugin’s Plus features enabled.

1. In RobloxStudio, enable the plugin and turn on the features in the Plus menu.
2. In StarterGui, create a ScreenGui and a Frame inside it.
3. This issue occurs in this specific game even after the plugin is uninstalled.
   

Expected Behavior

When I paste/duplicate UI or create new UI elements, I expect them to stay where they are.

Actual Behavior

Less than a second after creation, the UI elements are shifted (sometimes off-screen). Their AnchorPoint/Position/Size properties seem to be overwritten by the AutoScale plugin, even though I have uninstalled it (and briefly reinstalled RobloxStudio.)

Workaround

I have to manually reposition/resize the UI

The issue is now resolved, thanks!
EDIT: The issue is back, the uninstalled plugin is still making changes to my UI…
But I’ll reopen a updated report once I’m sure I have a more consistent repro.
