Problem with F3 and F4 menu DarkRP gmod 13

Hi, I have a problem with my darkRP in gmod 13, F3 and F4 menu does not work, when I try to Open it nothing appears on the screen, look at the console and saw the following error:

Type this into console

unbind F3
unbind F4
bind F3 gm_showspare1
bind F4 gm_showspare2

It will get rid of whatever commands are currently binded to F3 and F4, and bind them back to their original commands.
