intensity bug

We ran into the following bug, using a roadhog4 with 3.3.1 and just one internal dmx-output:

-chooser 10, channel 1 @40 in cue 1 and only this one is active
-chooser 10, cue 2 has only a comment macro 'FM2/50t20:GM2', which activates cue1 on chooser 2, this chooser has a priority of 10, the content of cue 1 is channel 1 @20 (so output is 10, because of fader is set to 50%); cue 2 (on chooser 2) is a follow, content is channel 1@full (so output is 50); cue 1 is a follow again, and so on.
-chooser 10, cue 3 has again only a comment macro 'RL2t20' (which was actually running on chooser 2)

When this third cue has a go, i would presume channel 1 should go in 20s. to 40%, from where ever the intensity was in the sequence . What happened was that channel 1 went to 100% in 0s. and after this the intensity decreased in 20s. to 40%. It seems to me that the fader-level is put to full in 0s.
