Thanks for your answers.
I don't know why, but now blockchain.info showing the same information like the other servers. Strange.
In my original email to support of blockchain.info I've included two screenshots. Below you will find the screenshot from blockchain.info.
However, I've tested this strange behavior in the last 2 days for a few hours. I don't know the reason why the information at blockchain.info sometime was not correct, but i'm sure that there was this difference.
Even if it has something to do with some browser caching (also my first idea), IMHO this is critical.
I've tested it on different locations, with different PC's and different browsers (Firefox and Chrome).
All I can say is, that it looks that this mismatch only occurs with valid Bitcoin addresses which were never used before.
That it is now not reproducible anymore, looks even more strange to me.
Before getting an answer from blockchain.info, or understanding why this has happend I prefer other blockchain Explorers over blockchain.info.
