Quote - Does P6 sometimes (or always) not observe the 'hidden' flag?

P6 and previous will unhide any morph channel that contains deltas, or to be more correct, reading the deltas cancels the hidden flag. If a hidden flag is placed after the deltas, the dial will remain hidden. However there is a catch to that strategy, any save and reload, ether as pz3 or cr2, will put the flag back in the original place above the deltas.

I was not aware that this bug had been fixed in later versions of Poser, as I'm still using P6.
