Tiramisu 2 Problem

I want to make a Tiramisu 2 server for me and my friends to play on.The server is maked with SteamCMD.I put the file on gamemode and the content on garrysmod as the instruction said.I also changed the gamemode on the start.bat to tiramisu,which is the folder’s name too.But for some reasons the gamemode is set to Sandbox,and not to Tiramisu 2.Please help me,i am desperate to play it.
