If that is the situation then it sounds like you need to submit a minimum reproducible case here. That way if you are doing something wrong it'll be easier to help and if you are not then it is something that can be investigated.
It wouldn't be the first time that a particular parameter didn't trigger an updater so needs looking at in more detail either way.
I don't know also what ChangePriority you are using. By description it shouldn't make a difference but the interactions between multiple updaters are quite complex.
