Hello @pcham26 and welcome to the customer community. Thank you for reaching out.
The issue is most likely caused by the Net Content & UOM - Vendor or the Net Content Equivalent UOM - VIP to Kroger that was added under the Classification Specific Attributes.
If you are using a spreadsheet to add/modify the data you can look at the documentation we have on SDL files 101 Basic - Spreadsheet Data Loader (SDL) in Product Introduction for Kroger or export an item that already has that data filled in to know which columns need to be populated for it.
Thank you and have a great day.
