Command + left/right arrow shortcuts do not work in Sierra

Hello.

After I upgraded my MacBook Pro (13-inch, Mid 2012) from El Capitan to Sierra, I found out, that hotkeys cmd+left_arrow and cmd+right_arrow stopped working in Finder. I used to use them to select items to the left and to the right of firstly selected since Lion release! Now, when I press any of these hotkeys, nothing happens, and only firstly selected item remains selected.

How can I restore previous behavior without rolling back to El Capitan?

By the way, shift+left_arrow and cmd+left_arrow acted differently previously, and I don't need Shift combination.
