ERROR: Invalid Password for key 'google play public key'

I've already been through this problem twice. I have my passwords for publishing saved in a secure area, and I know 100% the password is the same. I exit Unity, start it back up and doesn't want to accept the password again.

I select my Keystore, put my personal password into my 'Keystore password' textbox. It doesn't say it's incorrect password so it's fine. Then I select my Alias and put in my public key. It works and builds the game. I submit it to Google Play Store and it's up. Now when I exit Unity, put the passwords and Alias again, it says "ERROR: Invalid Password for key 'google play public key'". I know this is bullshit, and had to submit my app twice because of this.
