animate zoom in

So i have been working on a little movie with sprites and several years ago i stopped. Ive picked it back up and somehow I made the entire stage and sprites zoom in. The frame before as well as the frame it happens both says the zoom is at 100%. Does anyone know what I did and how to get out of it? As you can see frame 10766 is normal and at 100%. In 10767 its still at 100%. So I have clearly did something that made everything zoom in. Can anyone help?
