Server not changing maps

I recently installed a map into my servers /maps/ directory and when I go to switch to it (I have restarted the server, Multiple times) nothing happens.
This happens to alot of my maps and its bugged me too long.
Any help is appreciated!

Do the maps have capital letters?

Not at all

-Bump- Needs to be fixed.

show us your garrysmod/maps folder and how exactly are you trying to change maps?

Im using Ulx and console. Heres the pic:

The rp_downtown map is the one im trying to add
