Clan Matches do not count properly?

I've noticed (some other too) that the clan match wins and loses do not shown/work properly. Yesterday i just had like 20 Wins and 3 Loses,

suddently i've got 10 wins and 4 loses. The wins are reseted?

seems a bit buggy....

Well there are only 2 reason of loses for me, because some weird client errors like host connection problem. or we leave against hackzors. may fix the errors (client errors) ? They already exist since crossfire is out...

Sry, if this kind of topic already exist.
