Product Teams vs. Recipient in Workflow

Hi, I'm hoping someone has some insight into this issue: I'm doing some testing of a Workflow but I'm doing it in a dummy Product because I don't have a test environment. I've set it up so the people who receive Approved Promotion Requests are in a Group which are then put on a Role within that product. My intent was to set it up so that this group would only see "Promotion Approved" notices with the actual product line rather than the dummy Product. I set up the workflow initially so the Group would get the Approved emails, but then I saw notifications going to that Group so I removed it from the Recipients list of the Promotion Request Approval Notification and I noticed emails from the dummy Product were still being sent to this group.

After doing a lot of clicking around as wcadmin, orgadmin, and myself, I noticed that for whatever reason (confusion probably) I created the Role mentioned above under the Teams minor tab of the dummy Product, and not the production Product. My question is: do these Role contacts receive these notifications regardless what's in the Recipient list in the Workflow? I would have thought the Recipient list would ultimately define who received notifications but it appears that's not so. Alternately, is it possible that Tomcat/Apache/the server should be rebooted after adding/deleting groups to/from a workflow in order for the changes to take effect?

Thanks so much for any insight anyone can offer.
