I'm having a bit of a strange error and Googling around hasn't netted me any results.

Basically, I have several languages I use with Windows 10 and I want to be able to switch to them by number using the keyboard shortcuts. This was no problem before, but now that I've upgraded, bizarrely, numbers 1-5 won't save, but Alt+Shift+6 and +7 work fine. It's very strange. I've set the hot keys countless times, but they continue to get cleared whenever I hibernate my laptop.

Has anyone seen anything like this?
