Entities in config not sorting downward

Hello,

first time for me in this forum and I have searched for an answer but can’t seem to find it.

My problem is that when I add mulitple entities in the call service config window they add up on the right side which leaves me with a list of all entities to the right. Quite annoying when I want to add 5 entities. I attached a image to show you what I mean. Anyone know how to solve it?

Regards KJ
