Hi,
We made some "hot fixes" in the email in order to change some things in the emails. You can re-download HikaShop 2.2.2.
The two first problems should be fixed. For the last one I guess that is a translation problem.
Logically, we copy all new translations in the languages files so if you still have some "weird" untranlated texts, please check the language file (the english one is the reference).
Regards,

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