No XP on XP-enabled custom servers

I've encountered alot of custom servers that, despite being displayed with the XP-Icon in the server browser, don't yield any XP. It doesn't appear to be enabled at all, since the XP progress screen doesn't appear on round end.

I guess i'm not the only one with this issue?

There will not be post round screen for XP, it's post-match only. In case you have an issue with custom server, contact its administrator so they can fix it on their end.
