Been a while since I did any online with RF2 so this may have been present previously but no matter what i put in the filters, all servers show up. Upgraded from 240 to 298-300. perhaps a full install will fix, havent gone to that level yet.
This feature stopped working after the dns update from September which caused logging issues partially fixed by the update of the launcher. This was build 240. I havent tried in this new build but from your words it seems still broken. Enviado desde mi GT-I9505 usando Tapatalk 2
