2 days ago I installed a Bestway power steel AGP (13',3"x6'7"x39,4") on foam floor mats on our paved patio. After my son and I put it together, I checked if it was level on the top frame and (I thought) it was. After filling halfway I checked the water level and is was about 0,5 inch off max. So I thought it was OK, until I noticed a creaking sound on 1 side when I was in the pool yesterday. It appears that the patio itself isn't level (bumpy? I'm not sure if this is the correct word). I checked and put the (2 meter long) level on the top of the frame and it appears quite level but I now see it's not touching the frame in the middle. I can see there's more pressure on the liner there. Would it be possible to leave it up for a month or is there a high risk the frame or liner won't hold? I'll attach some pictures (the pictures with the tape measure are in centimeters not inches) Thanks in advance for your advice.
