Charge codes in Retail Receiving Errors

I am getting an error when I try and enter “Retail orders” not POS orders. In AX 2012, we could add charges to a sales order using a % (ie: 10% shipping charges). Now in D365, we receive the error: “Non-fixed charges are not allowed on sales orders from POS”

Technically these are NOT POS orders. I have a feeling b/c it is now a shared table on the codes there might be an issue. I am also afraid I am missing a setup flag that will call this issue.

Any thoughts are appreciated
