Copy into monitored folder with rename not working?

Using Hazel 5.1.1 on macOS 12.1
For testing, I'd like to create a copy of a file and then work with this copy. So I use the action "Copy to folder: monitored folder" and set the option "if file exists" to "Rename file". That should (I think) create a copy of "file" as "file-1" in the monitored folder (which I then subsequently can rename).
However, I always get the error message
Is that expected behaviour? If so, is there another method to create a copy of a file in the same folder?

- Code: Select all
Copy failed: Could not copy file: /Users/ck/Documents/Hazel/Test-Ordner/Bildschirmfoto 2022-01-19 um 20.44.48.png. Source and destination are the same`
