Hi StefsterHB
These fields are not ours 🙂
Our own custom fields can be identified easily because they have the ATUM icon inside. For example:
I guess those fields are being added by 3rd party plugins as they are not official WooCommerce fields either and, in consequence, we don't support them. So if you want to add them to Stock Central, this would require custom development.
Best Regards,
Salva.
