Mine does the same. The first few times I tried to push it back down, but it started getting crushed in a couple of spots and I decided not to worry about it since it seems to work fine. I thought about bracketing it to the bottom of the cooler, but decided against it. The stainless braid seems less and less permanent though - I'll probably build a manifold eventually. All that said, I haven't had any lauter efficiency issues with batch sparging and the stainless braid.
