ResignationApproval vs. AssignmentResignationApproval in BPM Worklist

Before enabling Redwood, the ResignationApproval task handled the workflow for employee resignations. Now, with Redwood, it seems that it's the AssignmentResignationApproval task, while the other has become obsolete. However, I'm facing an issue with the AssignmentResignationApproval task that I didn't experience with the previous one.

Issue = when creating a rule, I'm trying to include a 'simple test' using "Worker's Role Details.Role Name" as a condition. But every time I use it, the resignation fails.

Any ideas? Thank you.
