Image converter - wrong file name creation

I just used right click convert image (in same dir) and

Cube Elite C68X SLX (rechts)..jpg

will be renamed to

Cube Elite C68X SLX (rechts).-hd.jpg

With a dot "." before "-hd". I think because of a wrong file name parsing because of the ")"?
Used DO 12.32

Mysterious. I just did it 3 times. Copied it to another directory. Did the same but doesn't create the "." anymore. Needs more testing later.

That seems correct. There's already an extra dot at the end of the original name. The -hd is added after that.
