Issue occurs in both events and functions. Seems like it's only affecting Text, didn't notice this issue for other variable types.

The original actor is working as expected. Only the duplicated ones are impacted.

Issue does not occur in 4.25 therefore a regression

Steps to Reproduce
  1. Create a blank bp project
  2. Create an actor
  3. Create a custom event 
  4. Add multiple input parameters using Text 
  5. Assign a default value for each Text parameter
  6. Save actor
  7. Duplicate the actor 
  8. Open up the duplicated actor
  9. Call the custom event in BeginPlay
  10. Save the duplicated actor
  11. Right click and reload the duplicated actor

Results: default values of all text parameters are the same

Expected: default values retain their original value
