Finding discrepancy on work end date and stay duration

It is day 27, December 19, and the new Access Permit has been introduced to merge the identity supplement and entry permit.

Later in the day, a woman enters my booth claiming entry for work purposes, for a time of 3 months.

Checking the work end date on her Work Pass, I notice that the work pass implies that she's working for 4 months. I try to highlight the discrepancy between the access permit time and and work end date, but it solely gives me a "No Correlation" error. On this note, I quit the game and dash over here to pose my question.

How do you highlight the discrepancy between the work end date and stay duration?

Note: Highlighting the two individual values worked on the entry permit, but not the access permit.
