problems with overwriting

good morning,

since I installed the new version of TeraCopy 3.8.2 I have problems with copying files.

In fact, the "File replace dialog" screen no longer appears

as per link:

https://help.codesector.com/en/knowledge-bases/2/articles/401-file-replace-dialog

But automatically, instead of asking what to do in the presence of files with the same name, it makes a double copy of the files.

All this even if running "TeraCopy - Options under", "Transfer options" is set to "Prompt on filename collision"

Is there any other setting that needs to be set? Please it is very important.
