Grinder mounting in Krups EA8255

Hello. I took apart my EA8255 to clean out the grinder. It ended up getting moved around about while taken apart. I have cleaned the grinder and am putting it back together. I'm noticing that the grinder has three holes in it that seem like where screws should go. However, there are only two holes to receive screws. The third spot has a plastic post. There isn't anything that holds the grinder down onto the post.

Because the grinder isn't secured at all three points, it giggles. I'm wondering if I have broken or lost something.

I've done a lot of internet searching, and I can't seem to find an exploded view.

I have attached images.

Thank you,

Ariel

I hope you resolve the problem. If not I can post you some pictures of my krups.
