Editing assets.

So I'm trying to edit the drill sprites and animations to my own custom sprite. The thing is it works after editing the bitmap:

and shows up in TGB:

But when I run the scene I still see the drills moving rather than one frame(for now) of my own enemy sprite.

What am I doing wrong?

Also now when I restart TGB I don't see my own sprites anymore, it reverted back to the drills. :|
