Beans Falling under Drum

I got my Bullet R2 recently and I’m working through my seasoning roasts right now. I’m having an issue that when I dump the roast to cool, a couple beans will get tucked underneath the drum, where the arrows point in the pictures below. If I’m careful, I can get them to come out and fall into the cooling tray, but a couple of them have just fallen down. I’m not really sure where they went (presumably into the body of the roaster), how to get them out, and how to prevent this issue. Has anyone else run into this problem? I’ve looked at other topics about them getting stuck during roasting, but this is exclusively when I open the door to dump them for cooling. Any help is appreciated!
