How to fix UITableView Accessibility speak in wrong languge while scrolling?

I'm creating an app in Polish (Polish is set in iPhone settings). All VoiceOver text are said in Polish (like button, numbers etc.).

But when I scroll UITableView with three fingers it say in English: "Rows 1 to 10 of 16" (1, 10 and 16 in Polish).

How to fix it?
