lighting tech

[SorenDK]

I´m a newbee to the Zero 88 flx 24S desk having problems mixing scenes running from a cue stack with single cue playbacks. E.g. : I have recorded a cue stack with seberal basic lighting stages for concerts that I would like to mix either 1) with single playbacks recorded with different colours from our backlight fixtures 2) with different positions of moving heads. It works fine as long as the relevant fixtures are NOT recorded both in the cue stack and at the same time at a single-cue playback fader. The changes in light seems to be rather unpredictable and I can not figure out how to solve this. It might be that the option of mixing cue stacks and single-cue playbacks is not the right way to do it? Or could this be solved during record or playback settings?
