I have a CMR Workflow build using custom roles to separate my infrastructure group's notifications/approvals from my ERP group's notifications/approvals. When my technician is set in the "Change Owner" role, it seems to wipe the notifications which would typically result from my custom Workflow group. The same issue applies when a technician is set in the "Change Requester" role in addition to another custom role.

What would cause this? How can I resolve this issue?
