When you change modules they have to be coded to your car with Xentry or they won't fully operate. Presumably the shop you used did that.

@Montreal300 car is a 2014 which doesn’t require coding. The 2017+ cars do though.

CR is right on. However I think the modules have to be from another SL. No shop, I do my own work.
