Publishing to Gordon Food Service: Error Code "Attribute value must be in list

[SMCGINLEY]

I am trying to publish multiple items in item management to Gordon Food Service. There were prior error messages for something nonrelated, upon updating the items and sending a "change by refresh". Now there is a new error message coming up for almost every item, "Attribute value must be in list". I have not changed anything else nor have I ever seen this error message before. I have looked everywhere and cannot figure out what this means or what attribute they are referring to. Can anyone please tell me how to fix this? Please see examples GTINs below:

Hi @SMCGINLEY, thanks for reaching out again! We can confirm that a "change by refresh" error is simply requesting you to make a required update to the item data and then save. That said, we know the issue is an invalid attribute value, but GFS has not provided what that attribute or value was. 

Please reach out to GFS to confirm how they see the item on their end and to confirm what attribute is missing. 

Thank you,
