This thread is resolved. Here is a description of the problem and solution.
Problem: I am trying to Translate footer widgets by choosing the language inside the widget to be a language from drop down - screenshot below. When I choose the language and save it, it automatically change it back to "All Languages". And then I have all the language versions in my footer. https://cdn.wpml.org/wp-content/uploads/2019/05/3912963-Na_ytto_kuva_2019_5_29_kello_10.20.33.png?x34514
