Query: Does not hold the 2ds xl without it falling out

I purchased 4 of these for our 2ds xls. None of them will hold the 2ds inside without it constanly falling out. This creates a problem. They are too curvey along the backside to hold the ds properly, and the tabs that are meant to hold the ds do not do the job.
