Severe Divots: Is this an install issue?

Long story short: Had an above-ground Kayak pool installed in June 2022. We waited the recommended 2 weeks before getting in it and were very careful about "breaking it in" properly. The bottom was always a little lumpy, but this summer (less than one year after install) I started noticing serious holes forming. In the pictures below, every green mark is a divot that is 2-3" deep. These pictures were taken after I used a flat brush to scrub the bottom of the pool - the brush can't get into the crevices (ignore the corners and edges - hadn't gotten to those yet).

Kayak is saying it's not an install issue. They're blaming water tables, burrowing critters, and anything else to get out of fixing it under warranty. They say there would have been a problem sooner than now if it was an install issue. Thing is, I had another above-ground pool set up here for 15+ years with none of these problems - lumpy, sure, but no craters. Thoughts?

Wow. They need to fix that. Was there any attempt to scrape ground flat between old pool and new pool? How many inches of sand did they use? What kind of cove?

Interesting about waiting 2 weeks to get in - I’ve never heard that.
 
Did they wet the sand to help it compact & use a tamper?
P.s. you’ve got some algae going on there
The SLAM Process will cure that. You may need to use a house broom 🧹 to get in all the crannies.

I can't remember. I wish I'd taken pictures.

Yeah, the algae has been a constant battle this year, but I purposely left those spots so you could see the extent of the divots. This was after I used a brush to scrape the bottom. There are so many deep divots that I can't get the bottom clean without going into the pool and cleaning it by hand.
 
Have you checked for leaks in the liner?
You can do the bucket test it’s easy
