First off, Lets clarify :
-Using Magento ver. 2.1.1
-Got a Porto theme
-Only one extension other then the one for the theme: M2E
-Installation on Google cloud

We just got into magento, fidle with it a while and now we have something presentable. Except for one thing that really bug us.
See, I used the store view for the translation, didn't want and find the CMS file. Everything is good form static page to categories, but when we go to a subcategory and change 'store', the link add-up.

Let's say I got
www.domain.com/fr/category-fr/sub-fr
and switch "store", it will give me
www.domain.com/en/**category-fr**/category-en/sub-en

Anyone got a clue? Don't really know what could I say about which setting I got. got 'yes' for putting store code and thing. Their's surely something I'm missing right?
