SWBFII Modmaps on Remote Manager

[Anyder]

So, a clan mate called Simon, asked me today how he could start a server with modmaps, like Rhen Var Citadel in swbf2 with the remote manager.
He told me (and i saw) that all modmaps he wanted where in the AddOn folder and they were shown in rm, and that the rest was ok, but when he tried to start server with the modmaps, he couldnt see the server (me neither).
Does anyone have any idea on how can he host ?
Note: We can start the server without modmaps.
