When updating only header data on Purchase Agreement Change Order, approval errors out

Summary:

Purchase Agreement Change Order approval errors out when only header data is updated due to the Procurement Category Hierarchy Level 1 = Management... condition

Content (please ensure you mask any confidential information):

Are we doing anything wrong? It seems that it does not like the fact that we have both header and line attributes in the rule. If we make changes to the line, it works fine, but if we amend, for example, the Purchase Agreement description, it errors out.
