Automator Renaming in High Sierra: “...could not be replaced because it conflicts with existing file.”

I am using Automator to organize my music files on an external HD. I have many songs in duplication (depending on playlist) so the duplicates are there for that reason. I’m trying to replace the files that have “@0” at the end of the basename to remove that (I’ve tried check box for both “in base name only” and “in full name only”) but in the log return, I keep getting the warnings that “[Song Title] could not be replaced because it conflicts with existing file.” Is there a way I can fix this or create a script that ignores the fact there are duplicate title names? I don’t want to delete the dups., I just want to get rid of that “@0”. I have thousands of songs, so I need to use automation. Thanks!
