Is OK right now.
I have logged 1 cache on geocaching.com found before 8th Feb (my stats shown end period).
Today, in the morning I still saw 4132 founds, now I see 3457 = 2782+675, what is the correct number of founds, even the one recently logged is not yet included (expected behavior).
Strange, but OK now, so thanks Pleu for your assistance.
