Cant see weapon selecting

when i mouse wheel i dont see the gui at top of screen! it is making gmod unplayable. (admins i couldnt find any other posts like this, if there is link me then close thread)

Does it appear when you use numbers instead?

no, it is very confusing as i cant tell what items i have.

What gamemode and does this happen only on the server or clients as well?

DarkRP and on multiple servers but it isnt happening for my friends.

Only on DarkRP or on Sandbox too?

happening in sandbox aswell.
