AltGr+Shift switches input language only in one direction: EN->RU. Is it being treated?

Question

Keyboard layout

AltGr + Shift stopped switching the EN-RU language cyclically on Windows 7, and now it only switches to Russian - pressing it again does not change the language. In this case, the left Alt + Shift switches the input language "normally", in a loop.
Question: how to return the former cyclic AltGr+Shift?
Started after today's system update. The reboot didn't change anything. Reinstalling the Russian input language - too. The language switch manager is alarming, where only the left Alt is mentioned:

Windows 7 Pro SP1 64 bit, English, two input languages: EN and RU
