If im reading this correctly, the paver is sitting on the ground vs buried ie top of paver flush with original earth. I would fix it as the bottom track is now sitting on an inch of sand vs compacted earth. The cove will very easily wash out, liner will pop and you will have say 18k gallons of water going somewhere. The paver top should be flush with the ground,
the uprights sit on the paver and the bottom track sits on undisturbed earth, two inches of sand then go in pool.
