Food processor won’t store according to instructions?

So I got my first food processor since I’m tired of having to skip out on making recipes for lack of having one. I got the one with the best and most reviews at the target closest to me, a hamilton beach 8 cup capacity food processor.

It worked perfectly fine, but now storing it… it doesn’t seem to work according to the instructions? The instructions say to put the slicer disc ‘in’ the upside-down lid, on the top of the processor. But when I do that, it’s almost sliding off and it doesn’t really feel safe to store this way. Am i doing something wrong?
