Indesign 2025
When searching for a style for which I want to perform a change case operation, it works fine. If I then want to change the style that I'm searching for, when I confirm that change and return to the main window of find/replace, the parameters for the "change format" window get wiped out...I believe this only happens with change case. I tested this by changing the case in the Basic formats to "all caps". I found that if I used any other parameter, or any other parameter in conjunction with the new "change case"...the "Change Format" parameters remained...but when only using the change case parameter, "Change Format" gets wiped out if you choose a different style or parameter in "Find Format".

In short, the first time works. If you then try to change the Find Format selection, the Change Format selection for "Change Case" gets wiped out.
