Here’s the quick fix for this bug,

Open up Pie-Register.php in a texteditor scroll down to the function “Add2Profile()” inside this function scroll about 15 lines down you will see the following code:
$value = get_user_meta( $user_ID, $id);
replace the above code with the following code:
$value = get_user_meta( $user_ID, $id, true );

it worked
