Argon ONE v2 - Missing Screws?

Just bought an Argon ONE v2. Reading the instructions it comes with suggest there are supposed to be 8 screws: 4 shorter flat-head (supplied), and 4 longer round-head (not supplied).

The flat-head screws are suggested for attaching the boards to the top of the case, while the round-head screws are suggested for fastening the two halves of the case.

On the product page, it only mentions 4 screws, but to fasten the case (screw into the bottom of the case).

Have the wrong screws been included? Have screws been missed? It the product page incorrect?
Can anyone clarify?
