Hi,
I made several tests and I reproduced the problem you got. So I made a fix in HikaMarket.
It will be include in the next release. I am also working on the new HikaShop mail system (with new templates) and I will integrate directly this new system in HikaMarket.
It will allow HikaMarket to make better modifications in the mails (change some texts, variables and translations).
