Bug Report: List Replace Method

I still have the same problem James E. McBride reported in his thread (can no longer reply to it):
(https://www.advancedrenamer.com/forum_thread?for um_id=5865)

After closing the method window, the list and the "add"-button disappear.

If I add more lines so the scrollbars appear it works.

Updating to 3.86 did not help either.
