Thanks @lpb
I thought this could be the reason for the issue as I was facing similar in the past a few times, hence why I always set rules up separately in such cases.
My suggestion then would be maybe to test to set up the rule via the new rule builder in one of the projects where the issue is happening and see if that helps @Rachel_Roush.
Otherwise may be best to reach out to Asana Support so they can look into it in more detail.
