MoveTo Cue only Containing StopEffect removes StopEffect

In cue 587 I have an intensity chase running on three channels (Step based), in the next cue which is 590 the only information in that cue is StopEffect for those channels. If you do [cue] [590] [CopyTo] [CopyTo] [588], the previously running effect will track into 588 and disregard the StopEffect command.
