How to Ensure Symbol State Persists?

Okay, so I have a symbol that I want to show/hide; it's a named MovieClip with two labelled frames ("show" and "hide" in that order), the default is to be shown, and both frames have a stop() command.

This seems fine however at one point in my animation I trigger the symbol to hide via foo.gotoAndStop("hide"), but when the animation loops the symbol reappears (or rather, returns to the "show" frame).

Now, obviously this is annoying, but other symbols that function in the exact same way appear to be working as expected, so I'm at a complete loss as to why this one symbol in particular seems to be resetting? Is there some characteristic of the animation that might be causing Flash to see the symbol as if it were a new instance? I've checked that the symbol's name is constant throughout the animation, and I'm really only using classic tweens; certainly nothing that stands out as different in way compared to the other, working symbols.

Aside from completely re-creating the animation for that symbol I'm not sure what else I can try, so any suggestions are welcomed!
