Vocal Channel Compressor stops working

I've been having this issue quite a bit. The volume of audio files drops for no apparent reason. Turning the plugin off then on again does not resolve it. Not sure of a work around to get it working again. Seems to be random that it stops and starts back up again. Once I get one working, it usually happens to another clip somewhere else. Frustrating. Not sure if anyone else has seen this behavour. I did read one report of it happening in 15b3 with no other reply to that post. I'm using 15.0.0.086.
