Problem with adding server to favourites

[killer (LIMITED)]

Still cant add invex to my fav's for some reason i have have updated my config and stuff but it wont still let me. Pretty sure this is only a problem for combat surf because i can only add the invex 1v1 server and Jailbreak one.
I dont know why it just lets me add those 2 to my fav's. Unless there is other poeple that have combat surf as the favourites? Sir Lagalot Masta Byte
