Hello! I followed the steps on the other person who had the same issue, checked normals, applied scale, merged vertices by distance etc.
My bevelling isnt showing up on the back and as soon as I apply any weight the cartridge ridges it seems to mess up my bevelling on the buttons on the front even though they are 100% not selected when changing the weight.
Also adding just using the normal Bevel tool it seems to shape normally so I think the mesh is okay.
oh cool, thanks for this. So, hm, ya just doing a non-modifier bevel works somewhat better but not perfect either. For me I'm going to leave it un-beveled and move on, but I am curious for the solution if it comes up
