Restore iphonefrom encrypted backup

Need a little help.

Got my iPhone 6s plus today so I backed up my iPhone 6 to This computer selecting Encrypt iPhone backup so the passwords, Health and other things would back up. After is was finished, I went to iTunes> Preferences>Device and it showed the encrypted backup.

After starting up my iPhone 6s Plus, I go to restore and the encrypted backup is not there as a choice. It is still listed in devices.

Any ideas???
