It's not normal, but that looks fixable yourself. The B pillar 'inside' is plastic covered with cloth on top, plastic on the bottom. It clips into the B pillar. You could make sure it is clipping in properly and use a spudger to make sure the lip of the plastic trim isn't being pinned behind it. The trim should lay on top.
If that didn't work, I'd Mobile Service it, because it is not right.
