Reproduced 3/3 times. Issue does not occur in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed Regression.

Steps to Reproduce
  1. Create a new C++ actor
  2. Add an EditInstanceOnly UPROPERTY & a VisibleInstanceOnly UPROPERTY
  3. Set a default value for both
  4. Save & Compile
  5. Create a Blueprint based on your C++ actor, add one to a level
  6. Open Blueprint's Class Details

Actual Result: Both UPROPERTIES are displayed in Blueprint Editor, and the EditInstanceOnly UPROPERTY can be modified, which affects all existing Instances

Expected Result: These UPROPERTIES should only be accessible/visible in Instances
