Hi,
The "each" is not managed by HikaMarket, your question is related to HikaShop only.
And you can edit the HikaShop language translations in HikaShop starter, you do not have the limitation that you think.
You're free to override the translation to hide the "each" ; in the HikaShop configuration, tab "language".
Regards,

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