This one:
<string name="prefs_view_list_round_images">Okrągłe zdjęcia kontaktów</string>
Was like this, wrong:
<string name="prefs_view_list_round_images">Przeciąganie</string>
I've just corrected it, sorry.
The other two you've listed seem ok:
<string name="prefs_category_swipe">Gesty</string>
<string name="prefs_category_search">Wyszukiwanie</string>
