IES Lighting profile and function pack

Hi I just got this pack and tried using it in a 4.17 project. I loaded up your example map but I get the error too many overlapping shadowed movable lights. Also the profiles don’t seem to work as you can see in my screenshot. Is there some setting that needs to be turned on in the editor or is it a 4.17 thing? I’m going to test it out with an earlier engine.
