Today I won 2 correspondence games and lost 0, but I lost very much rating. Is it a bug with the rating system?
ok, I understand, that I had current rating upper than when I started games, so rating could be recalculated, but it shouldn't decrease by winning games, should it?
Or, maybe, this page doen't show real rating?

As you say, correspondence rating is quite confusing, as the games are very long, and one plays many at the same time, possibly with different start ratings. I am not quite sure about all the details of the current implementation.
And then I think those stats in the timeline may have a weird behaviour because of cached values, and what rating is used for comparison, etc.
As a bonus, you don't have an established corr rating yet.
If I remember correctly, there were multiple threads over the year regarding this. The bottom line was: you don't lose rating when winning games, the summary may show "wrong" values. Your current rating is the one to trust.
