T4 2023 Requirements - Box 45 for individual who was no longer an employee on Dec 31

Hello.

As per new T4 2023 requirements, Box 45 should be left blank for the individuals who were no longer an employee on December 31. 

I can't found the way to leave this box empty. Sage gives me options #1-5 and when I try to delete everything from this box, it automatically comes back to option 1.

How to fix it?

Thank you,

Svitlana.
