Changing Effect Rate Via Encoder causes effect issues.

Changing the Playback Rate of a cuelist that has a running Cue with a effect on the dimmer via the encoder wheels (accessed from holding choose) causes the running effect to glitch.
I can send my show file if that helps, I've experienced this issue before but it's a pain on this show and would love to find a workaround to changing the speed live.

*what i've observed: On the DMX output window, the Dimmer channel for said lights running the effect goes from 0 through 255. When I change the playback rate the dmx output window displays 127 through 255. Not sure what cuases the lowpoint of the effect to do this.
