Default Advanced Delivery Screen Bug/Crash

I have a very annoying bug that makes the default advanced delivery setup unusable. When you have multiple departments and switch between them sometimes just once other times 2-5 times it crashes with the following report. I created a brand new database… created a simple create ticket department and another department with delivery screen and issue occurs.

Edit: I fixed it by recreating the entity screen from scratch. Might be a bug of importing the entity screen via configuration task. Still might want to check this out.
