Missing Korean business registration number error!

Hi. I added 10x zeros (“0000000000”) in the Korean Business Number field which solved most of this for me. Once done I thought the issue was fully cleared with Google Merchant Center (GMC) but when I looked at the Products section in GMC I could still see all my products needed attention due to missing Korean Business Registration Number. I then made a small change to each products description (such as adding a space at end of the product description text) which seemed to refresh the results. All alerts for Korean Business Registration Number have now disappeared. I now only have ‘Unsupported currency’ & ‘Missing or incorrect shipping costs’ to fix but that’s a different topic.
