new update affecting fader

After doing an update I press go or flash with fader in the full position it does what its supposed to. But when I manually pull down the fader it doesn't dim. It go's all the way down to zero than lights shut off. No dimming. This happens when the play or flash button is hit and at that point I lose manual dimming ability. Fader just shuts lights off at zero anywhere in between lights stay at `100% full.
