This worked for me yesterday for leatherworking when I used this addon for the first time. I thought maybe the new version today caused it to fail, but I really don't know this addon well at all.

I did a reload and it worked so I have a work around. Also I can now track or untrack this recipe or any other and it works.

Hi @EyeSage, is this on the 003 version? If so, this bug is likely resolved in the 004 version. I'd messed something up in that version that caused the list to bug out after using /psl clear.

Can you verify the bug is not present in the latest version? :)

Yes it works correctly now on version 4. I got the error on version 3.
