Trying to add nzbget and getting 'Password' should not be empty

I tried the latest master and development release of nzbdrone (sonarr). If I set nzbget to not use security it works fine. If I have security set and put in an username/password I get ‘Password’ should not be empty no matter what. The password field isnt blank and is correct. I am entering in the correct username as well. Any ideas?

I can’t reproduce this on latest develop, exactly which version did you try?

If I leave the password blank I get that error, but not when the password is set.
