Panning Automation Without Making Pattern Unique

I want to create a panning automation to a pattern that is reused around the song. However, the moment I add a node in the panning automation edit chart, it makes that pattern instance unique (i.e. changes the number etc). How do I prevent it?

not sure why it’s doing that. I tried and i i automate it keeps the same pattern number.

never happened to me, and I don’t know how it could happen
