Strobo CUE doesn't return to original state

[Johanvh]

I progrommed a CUE where I enable the Strobo/Shutter effect on many fixtures.
When I run this CUE by a button in the playback pallet, all fixtures start to active theire strobo effect.
When I release the button (set as flash), some fixtures stop the strobo effect and remain there 'previous animation' but some fixtures remain to strobe and when I have a look in the DMX pallet, the strobo channel doesn't goes back to 0.
Any idea why this happens?

This is correct behaviour. All channels are LTP (latest takes precedence) except dimmer which is HTP (highest takes precedence). Set the release mask for the strobe playback to include shutter via [Playback Options] (you will probably also want to set the release time to 0s).

Thanks Nic,
I tried your suggestions and now it works as I want it
