to modify a cue in a unbloked cuelist

i'm using hog pc v3.4.3.89 and there same trouble on hog II.

I have a unbloked cuelist and i want to modify a cue, i load the cue X, i change value and i update the cue.
Now if i load next: cue X+i, i can see olds values that did not appear before.

exemple. my cue 1 is in @0% in red and my cue 2 is @ Full in red so cue 1 is 0% + red and cue 2 is full.
If i change cue one in 0% + Congo, the cue 2 will become full + red, so i must changes cue 1 and all cue that must stay like cue 1.
I should have to change only the first cue and not all those which follow.

That is the same if i put one new fixture in cue one @ full in cue 1, it will be @ 0% in cue 2.

what is that I do not make well?
