Can't Delete a Tag - Opto Control

I have removed a tag from the program, however it still shows up as being used 1 time, therefore I am unable to delete the tag.

Press CTRL+R to rebuild the reference counts.

Thanks for your reply.

I tried the Control R function multiple times, and observed it working, however no luck.

Still can’t delete the tag that does not exist.

Not sure then - have you verified it isn’t being used anywhere using the Find command?

Yes, that was the first thing done. I kept searching and finally discovered it was used in a PID loop.
Apparently the search does not find it if used there.
