flow works for 1 field but not for the exact copy af another

Hi everybody,

I've been staring at this for 45 minutes, but i can't see why it's not working, so maybe one of you can help me.

I have a flow set up that updates the details of a creator form report with the details of the customer in the CRM. However the flow fails on three fields. One of which is exactly identical to another field for which the flow DOES work. And i can't see the problem.

My Genk classes in the CRM are linked to the Genk classes field in the form. This works
Multi-picklist in CRM

multi-picklist in Creator form
So this works, however I have the exact same setup for my Maastricht classes, but if I enable this the flow fails.

Multi-picklist Maastricht in CRM
Multi-picklist Maastricht in Creator
So if I enter the same custom value in the flow in the Maastricht field as I do in the Genk, the flow fails.

2nd one works, the 1st one won't work
What am I missing here? I really can not see it. I have the same problem with a multi-picklist where the customers can choose a day.
