kinda pissed at my contitech bags

So today i finally hacked up my front spring pockets and got my shit to lay out but i found a leak in my contitech bag near the band in the middle. It hasnt been exposed to rediculous pis or any spakrs or fire but i aired it up and it was leakingout of the side.

After i got it on the ground and aired it up it held air and didnt leak even when it was fully aired up. Now is this a manufacturer defect or is it somethind i did.
