Error: Package Dimensions must be greater than 0

I have WooCommerce Shipping setup and it has worked flawlessly, until today, when someone bought 6 of the same item. The cumulative weight was calculated but the dimensions were shown as 0x0x0 with no way to change that number and no way to proceed with shipping the item until that number was changed. The weight and dimensions are correctly supplied on the product page under Shipping. There needs to be a way to alter dimensions the same way there is a way to alter weight.
