how to include adademic title in personal information approval

Hi together,

We're facing following problem:

We want to include in one rule

Current Person GlobalName.result.FirstName != Proposed Person GlobalName.result.FirstName

AND Current Person GlobalName != null

AND Proposed Person GlobalName != null

OR

Current Person GlobalName.result.LastName != Proposed Person GlobalName.result.LastName

AND Current Person GlobalName != null

AND Proposed Person GlobalName != null

OR

Current Person GlobalName.result.Title != Proposed Person GlobalName.result.Title

AND Current Person GlobalName != null

AND Proposed Person GlobalName != null

--> The first two rules with "FirstName" and "LastName" are working.

The rule for "Title" isn't working. We want to include the change of an academic title in the same approval workflow.
