Front-end translations missing, help needed

After installing and enabling language pack for HikaShop Essentials, everything isn't translated properly (see attachment). Requesting assistance how to manually complete translations?

Latest Joomla and HikaShop, also updated latest available language pack as suggested. Running HikaShop on Favthemes Viewpoint solution (latest version).

Hi,

The "login / register" link isn't coming from HikaShop so adding the HikaShop language pack won't help with that.
And I suppose that the cart link is something coming from your Joomla template so it's the same too.
You'll have to check with your template provider on how you can translate these.
