Shortcuts don't work

I decided to give SwiftKey one more chance and it's just useless. None of my shortcuts work. I try to swipe my email shortcut and it spits out some random word I've never used in my life. Half the time when I swipe it puts down a single random letter and then starts some other word. It always puts a space after words and full stops no matter what, resulting in usernames and passwords with spaces after them so I can't login, apostrophes after a space so I have to backspace to show simple possession, and spaces in the middle of email addresses because they contain a full stop. This is utterly ridiculous. Also I had to backspace at least twenty times typing this because of the damn one letter issue. My typing speed has gone from a sentence a second with GBoard to a sentence a minute with SwiftKey. And that's slower than a computer.
