Hi,
Once the translation won't be accessible in Falang we will remove it from HikaShop/HikaMarket.
In Joomfish, some people were complaining to not be able to edit the translations they made in the Joomfish backend, so we added the main language to let them access to every elements that they could edit in the backend.
Otherwise, they could create a translation in the joomfish/falang backend and they don't see it (and don't have the possibility to edit it) in HikaShop/HikaMarket.
It is like that for many years in HikaShop for the integration of Joomfish (and so Falang).
