The trim piece around my shifter console keeps popping up for some reason. This is not a photo of my car, but just a stock photo with the arrow pointing to the trim piece......

Does that trim piece have an official "top and bottom" to it, or can it just go in either way? It has 4 clips that protrude from it that grab onto something. Why would mine be popping out? I'm wondering if one of the plastic clip prongs broke off after I removed it.

My car is a 1991 300d.
