Can you please specify the OS you're playing the game on and the game build version (should be visible in the main menu)? Also, you can always use a mouse wheel to change items!
I'm on Windows, on version 1.1.10. The hotkeys also don't work for my friend who's on the same OS and version. Mouse wheel does work and is nice, but when spamming keys for fast dialogue hotkeys are nicer :p
