Priorities with Submasters and Cues

I am working on a show that is running cues, and then we are adding in submasters with effects as such. When we run cue 1 and then added in submaster 1 with a color effect, everything is working fine. When we press go on the cue list, the color lights follow the cue and stop on the effect, even thought the effect is still running. I did look at the priority on the cue list and submaster. the cue list has a priority of P4, and the submaster is P5. If anyone has any knowledge on this, and would be able to share that would be very much appreciated.
