Is there supposed to be movement in the electronic distributor pickup plate?

Hey guys, my 360 lost spark in my Dart. It has a mopar performance conversion kit, I bought some years ago. I never paid any attention before but noticed there is movement with the pickup plate, both side to side and up and down. The screw is still tight but not sure if the movement should be there or something is wrong? The reluctor looks brand new too so I don't think the movement is enough to hit anything. Just wondering if it's my ECU or the pickup plate. Any help is greatly appreciated, thanks for your time.
