A couple Gmod hosting questions

I have two questions. My server is rented from Xenon Servers.

  1. My server came with maps for tf2, DoD, Portal, etc. How do I get those maps out of rotation? They are not in the maps folder. Is it possible to make my own custom rotation with ULX?

2)This question is specific to a gamemode, so I’m not certain it can be answered here. In the gamemode Trouble in Terrorist Town, the scoreboard is fucked up. A lot of things overlap or do not appear at all.

Any help is appreciated.
