I bought a package of Pi zero W in here and it comes with a case made from Adafruit, but when I'm assembling Zero W into case I found out there is a piece that bump out at the back inside the case (the side where you can connect pins on zero W but it's on case) and if you put that piece under Pi, Pi can't nicely fits in, but if you want to match the four side it provide to lock you Pi in place you can't because you can't put your Pi under the bump out piece
How to solve it, shoud that piece be above or bellow Pi or should I chop it of
