Using Thru to define Flexi View Channels doesn't respect current Flexi mode

3.1.1, but also 3.0

Live tab currently in Flexi Active, some non-consequitive channels are on, e.g. Chan 1+5.

Chan 1 Thru 5 ViewChannels

Live tab with new Flexi mode active shows channels 1, 2, 3, 4, 5.
i expected to see channels 1 and 5. when defining the view channels only channels 1 and 5 were selected.
if i had wanted channels 1, 2, 3, 4, 5 on screen i would have used Chan 1 Thru Thru 5 ViewChannels.

thx, ueli
