If you see % (ampersand) in your date field, which is part of the profile plugin (date of birth field), you can fix it easily with editing the file plugins/user/profile/profile.php. The line currently (2.5.1) is:

$data['profile']['dob'] = $date->format('%Y-%m-%d');

and should be changed to:

$data['profile']['dob'] = $date->format('Y-m-d');
