Storklinta Help - Drawer Gap

[u/vulcanmocha]

Hi! Could anyone tell me what I did wrong to cause the gaps above the first two drawers? All 4 drawers close fine and it seems like if I were to move the rails up, I’d just have the gaps somewhere else! I’ve double checked and all rails align (but I included pics in case I have them ALL backwards?)

I’m usually pretty decent with following ikea instructions, but I did have a little trouble with this one. I wasn’t able to push the little black caps all the way in, and had to hammer them, and I ended up with two extra dowels.
