Operation lists running simultaneously despite being declared in exclusion groups

We are seeing evidence at a client site that operations that should be blocked by an exclusion group are being run at the same time. For client privacy reasons, will provide screenshots via private comment describing the group and showing the clash.

We've done an analysis of the UNIFYNow (Version 3.2.0) schedule and don't see other operation lists that could be triggering the runs we're seeing in MIM but we can make the config file available on request.
