RCA ports a bit fragile?

There is a gap between them. Zoom in and the letter U is visible.

Yes, but that's not necessarily the thickest part of the plug. It's just a little hard to see.

The plugs are not blocking each other, are they? If you plug in the left one first it still sticks out a little?

I tried to make two attempts but the left side always remains behind, however everything works perfectly, so I don't touch anything anymore!
