ABAHUB: FIN INSTALLATION

Just received my Abahub board love it!! However on first use checked it out after inflating it and there is a spot on the bottom side about 8 inches from the the front point that seems to have a bubble the size of a half dollar. It looks as though the outer quilted skin is pulling away from the lower layer, the “quilting” is gone and the bubble is smooth. I fear this will spread with time and pressure. Can someone give me some insight on this? I hate to have to return it, I love this board!! Awaiting your response!! Thanks!
