How to sort the customfield of a product in the backend of the product

-- url of the page with the problem -- : autovakshop.trainingjoomla.nl/
-- HikaShop version -- : 5.0.2
-- Joomla version -- : 5.0.1
-- PHP version -- : 8.1.25
-- Browser(s) name and version -- : Edge

When I entering a custom field, I can cahnge the order of the field. The order is showed on the frondend as expected.
But when I edit the product in the backend the ordering of the field is based on the ID of the field instead of the order_field.

Is this done on purpose or am I missing someting? It should be nice if this follows the frondend. Reason, somtimes it customer friendly to have them in the proper order. Easiers to mange fot hte end user. Especialy when you decide to add later an extra field.

Is this possible? In the attachment yo see the custome fields which the order (sort\) vanue behind it.
