Are the resin caps supposed to be flush. Some are and some are not. Especially on the side of my oval. See pics. First pic is all the way down the side. Second is a close up and third is one that is nice an flush at the end of the pool. My concern is water getting under and down the mental post causing rust. HELP is this normal or ok? There is no water in the pool yet.... Maybe it will straighten out with pressure>>>>> PRAYING
