Copy: rename and append greyed out

[Fufurro]

Hello! I'm using multicommander for quite a while now, and I just noticed that in the copy/overwrite popup the options to rename and append files are greyed out.
Is there a setting that I can change to enable these functions?

I'm using the latest version on Windows 10.

Thanks in advance!

Normally they are enabled. But depends on device type of source and target volume

After additional testing, I report the following:

when moving a file in another location of the same partition and in the destination folder the same file is already present, the options to rename and append are greyed out.


Is there anything I might change in the settings or is it something you will investigate?
Thanks
