As far as I can tell, this is true. I'm not a sub, and it appears that I can only have 15 conditionals in toto.
Once a conditional move is played or deleted your should be able to make another.
Yes. As a non-sub, you can only have six games running anyway, so it isn't quite as much of a problem as it seems.
Note, though, that while conditionals are deleted when they are no longer possible due to a change in material, conditionals which can no longer be played because, for example, a pawn has advanced stay in the cue. You'll have to delete those yourself.
