Texture Paint Problem

So i got this thing where sometimes my mesh only has one face in texture paint(it only sees it as one face) and instead of letting me paint what i want on the mesh it paints it as a whole. This is also the case for selected faces only painting. It only sees the original cube and not the mesh that became from the cube.

This is what it does and its really frustrating

It looks like a problem with the UV, but I can’t see your UV.
