I'm doing a simple animation mockup and for some reason, a section of the smart object layer won't stay. The animation is simple. The iPhone just moved right then back left again. The bottom corner seems to always reset its position. No matter how many times I change the position once I move the timeline the size resets again. Any suggestions? I've been trying to google suggestions for 2 days straight and found nothing so far. I recorded my screen so you can see what I'm exactly doing. and I also provided the original file below just in case you would like to test it out yourself.
