Issue with tank not sitting flat

[blennyhana]

Brand new Tideline 62 gallon rimless AIO lagoon with a reinstalled leveling mat attached. We noticed that the ends of the tank seemed to be raised up which caused some concern regarding filling it up and having uneven weight across the bottom cause a crack. At first we thought our stand was not totally flat but upon placing the tank up on our countertop which is definitely flat and double triple checking with a 4foot level used as a straight edge. The ends of the tank are definitely elevated. It seems like all the pressure is in the center. So I’m concerned that once filled the center portion of the tank is going to be at an increased risk for a stress crack. We sent a message to Planet Aquariums so hopefully they get us some answers. Anyone else ever run into this? Photos below.

Could it be that the mat itself wasn't cut flat/has major uneven spots? Those "should" compress after filled but I would rather try a new mat since none of the ones I've used on any size tank has ever looked like that.

That’s what we’re assuming and hoping is the case. Can’t imagine the glass could be off. Just seems odd that a messed up mat would create that big of a gap
