Celebrate Vitamins review for Walmart Marketplace

When using this app to submit products i only receive feed errors with no defined field. The error i receive is Error type = Data Error | Error message = Exceeded maximum allowed characters for this field. In the app this message shows under the product / variant name. I have opened multiple tickets and have not received a response on any ticket (Started first ticket a week ago). Hopefully Walmart will respond to this message so i can get this working.
