Hi,
What HTML formatting problem are you talking about ?
I may have missed it but the only thing I saw is a difference in the "tabs". In German the texts are wider so it took two lines.
Logically, I don't think you are talking about it because it does not have any link with the HikaShop 2.2.1 upgrade.

By the way, do not send me private message, use the "contact us" form instead.
