If things are bouncing around, that's likely the lazy loading kicking in, which is something completely unrelated. Just wait until everything's loaded and then you should be able to edit. If you're still having problems, then you should Contact Wikia. Make sure to tell them what device you are on, what browser you're using, etc. and what's not working. A screenshot or video would help solve the problem faster.
