Current Assignments and some Tasks and Actions functions not showing after being placed on hold

We recently installed SD 8.0 HF2 but we are having an issue that once Incidents have been placed on hold it seems like the incident corrupts and the current assignments as well as some of the Task and Action options are no longer available. The incident cannot be removed from hold and even when removing it from hold by updating SQL tables the options do not become available again.

Has anyone seen this before and were able to successfully resolve this issue?

This is what it looks like when it is fully functional:
