Hosting Issues

I am having trouble hosting a server. I have forwarded the correct port, and the server even shows it's name, the IP address, and the version in the Master Server listing. However, it doesn't show that the game is modified, it's ping, the players, or the gametype.

Does anyone know what the problem could be? Thanks.

EDIT: I've also tried to give myself a static IP, but it seems that it did nothing.
