Hello - I've filled my 24' round Intex XTR, after having to raise up a few posts on one side about 2-1/2" to get them all level (within 1/4"). I noticed that there is some "sag" of the liner directly under those same posts (picture of the worst one attached). Is this from the liner "hanging" from the cross-bars because of the raised posts? I'm a bit paranoid about this pool...
