Notifications to people in specific Custom Orgs

We are doing a Distribute Document task for lawyers in the UK. The way we're differentiating the groups is through custom organizations and using the Distribute Document BP.

We want to send out different completion notifications to the different groups based on what custom org they are in.

I have a Business Process condition on the notification to say "Custom org any in sel list is "Partner" " on the notification, but it is still not firing despite the employee being in that correct custom organization.

any thoughts?
