Newbie needs help with 33 round rail/wall coming apart

[KMKjr]

33' round above ground pool.

Liner is still locked in wall but wall popped out of the top rail after second load of water.

Fitted liner and just installed.

Pad, top and bottom within 3/8" all around.

Hi and welcome to the Pool Forum. I am not a pool installer so can't really help with this but once your registration is complete and your post gets moved out into the general sections of the forum, one of our installers should be able to give you some advice. I just wanted to say hi and let you know that your post has been read and you aren't being ignored! Hope you enjoy the forum.
