Are you seeing filters like "Non Elite" and "Complete crew"?
If not - then no, it's not working properly. Because the XVM team disabled the filters till they can fix it.
Hehe, the reserve is part of the filter stuff, so yeah...
If you want to take them off reserve again, you can by deleting the file here:
%AppData%\Wargaming.net\WorldOfTanks\xvm
There's a file called something with "reserve"
