Specifications on product view for multi lingual website

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.4
-- Browser(s) name and version -- : all

Yo community. I'm attempting to build a website for a client in order to propose switching from Virtuemart (ehh) to Hikashop. I am building bi lingual website with Latvian and Russian languages. I am using Falang. Everything seems to work (all content is working perfectly, like custom fields/bi lingual product description and multi lingual search). The one last bit I need to get working is the following:
I need to have multi lingual tabs. In the screenshot below you can see a tab called "Apraksts" , in Latvian it's product description, and it works in both Latvian and Russian, like you can see in the screenshots below. The right tab (Specification) appeared out of nowhere (John Cena refference...) in latvian it's "Specifikācija" ("'Характеристики"' in Russian). Even thou I don't recall creating it, I still need that Specification tab. Basically the idea is that there will be a multilingual tab with description (got it working now) and a multilingual tab with specifications (i dont know how, but the tab is there but I have no idea how to edit it). Can you please help me ?

Weird thing is that I do not have any custom fields made apart from the "shortproductdescription" but I've chosen not to display it on the product page. Here's the list of my custom fields.
