Thanks again to everyone who replied. Just to follow up with everyone on what we did. We dug out by hand the section that was bowed out. Then we gradually slid the brace down bit by bit. When we got it back to line straight, we returned the gravel fill. It seems to have worked. We poured the collar yesterday, and we are doing the coping and decking next week. I guess we’ll see how well it does when we remove the braces.That’s plan B. The builder said he had the same issue on the same model for a pool they did last year. I’ve looked at their finished product and you can’t tell.
