Custom profile fields doesnt show values

I chose this option:

and added the code to my functions.php:

function modify_contact_methods($profile_fields) {

	// Add new fields
	$profile_fields['tel'] = 'Telefon';

	return $profile_fields;
}
add_filter('user_contactmethods', 'modify_contact_methods');

and added this field to profile-form.php:

<h3><?php _e( 'Contact Info' ); ?></h3>

		<table class="form-table">
		<tr>
			<th><label for="email"><?php _e( 'E-mail' ); ?> <span class="description"><?php _e( '(required)' ); ?></span></label></th>
			<td><input type="text" name="email" id="email" value="<?php echo esc_attr( $profileuser->user_email ); ?>" class="regular-text" /></td>
		</tr>
		<tr>
			<th><label for="tel">Telefon</label></th>
			<td><input type="text" name="tel" id="tel" value="<?php echo esc_attr( $profileuser->user_tel ); ?>" class="regular-text code" /></td>
		</tr>

		</table>

when I update this field on my profile page, it is updated in database (backend) but when I refresh my profile page, it shows now value (its empty in frontend). If I hit save button again, it will remove this field value from database.

What shall I do to fix it?
