Custom Fields Don't Delete & Information Isn't Stored

Here is the quick work around for this problem:

open pie-register.php in a text editor:

go to function SaveSettings
search where it reads:
$custom = get_option( 'pie_register_custom' );

Replace it with:

$custom = '';

Thanks

Don’t know about not being able to delete the custom fields, i think that works, but mine doesn’t store all the information (random).

I checked the pie-register.php and it’s already $custom = ”;

any ideas?

BTW: Why can’t i order the Custom Fields?

P.S.:
I deactivated all the plugins but Pie Register (Version 1.31.3), i have WordPress 3.7.1.
