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
Results: default values of all text parameters are the same
Expected: default values retain their original value
There's no existing public thread on this issue, so head over to AnswerHub just mention UE-105022 in the post.
