cmd.exe - Windows 10 - typing numeric characters fails

I have an annoying problem with cmd.exe on Windows 10. When I type something on the command line, all characters appear fine as typed. Except for the numeric characters of the main keyboard. Numeric characters of the NumPad also appear fine. When I type a numeric character on the main keyboard, its 'shifted' character appears. Holding SHIFT key while typing doesn't do anything. Only when I hold LEFT ALT key while typing numeric characters, they appear as they should. If I run cmd.exe with Administrator Rights, everything works fine! But I do not want to permanently set cmd.exe to start with Admin Rights, because then I always have to type in the password. In every other program on my pc, I do not have this problem.

Any ideas?

Thanks to @JW0914 for pointing me in the right direction of the solution! I use TypingAid (the AutoHotkey autocompletion tool) to 'autocomplete' when I am typing. TypingAid uses the main keyboard numeric keys to let the user select which word to use for the autocompletion. Disabling TypingAid immediately solved this problem!
