Hello! My bf bought a Coleman oval pool 16x10 pool while I was away and set it up without reading or putting much thought into it. It wasn’t level at all. I got home and major panicked. we drained and moved it to a (almost) level spot. We followed instructions and the water level is only off about 2 inches. We put the side outriggers on wood boards (as well as the legs) as shown in instructions but I now I feel the liner isn’t resting on the ground enough .. also having some bowing on the top rails.. is this because the out riggers are too high off the ground ? Help any advice is greatly appreciated.. I may have too much anxiety to be an above ground pool owner 
Overall things look pretty good. In pic #1 though, is that gap at the bottom before the water was added? I can't imagine there being a gap with all the water weight inside.
