My password keychain will no longer autofill passwords on safari, why did it stop all of the sudden?

Ok so I restarted my computer and now Safari will not fill in my passwords, I checked that autofill is enabled, all the usernames and passwords are still listed however it will only fill in the username of each site. Its not site specific it does this to every website that I need a login for. I also made sure I checked my password keychain and it still has all the same information, passwords and usernames stored. But still it refuses to fill in the passwords. Why did it stop all of the sudden and how can I make it re-enable itself to fill in my passwords again!
