weird issue while working off of a capx

I am working off of a capx file replacing my own game content into it. However, something weird is happening. When the game starts, for a second, the sprite I designed is shown but then quickly reverts back to the old sprite and remains that way. I am not sure what might be happening. Any help would be appreciated, thanks.

I can't do urls yet but here is a video of what is happening youtube.com/watch?v=4pA8oYc6tu4

It seems to be when my sprite starts falling. right at the start it is fine but once my sprite begins to fall down it changes to the old sprite.

Maybe the sprite has multiple animations or frames and you only replaced one of them?

You were right, the animation window was coming up behind the edit window so I couldn't find it. Thanks!
