device does not insert in PCI-E slot

The bare plastic down extension(has FB2 printed on it) seems to block
the physical insertion into the PCI-E slot so the card seems loose and not well secured.

Hi Eugene,

Thanks for posting! If the card doesn’t fit right in, something is off - you don’t need to force it.

Just to make sure there’s no confusion, this is the the product, right:… ?

And can you describe more about the plastic extension? Is that part of the green printed circuit board, or something else? What color is that plastic part?

Thanks for providing this extra detail, so we can tell what’s different from the norm.
