[Plugin: Polylang] widget text and flags in custom menu

Hello,

I am using plugin Polylang to translate content on my website.

I have a few enhanced text widget areas, and they work perfectly well in english, but after I translated them in String Settings (I wrote new texts for all widget texts and titles), only titles were translated.

Second, I tried to add language switcher in my custom menu in header right widget area. Not only it does not work, it shows a single flag of USA, and I dont want USA flag to be on the page that is already english.

Please help, I am nearly done with my work, this is all I need to finish.
