Error with charge codes in AX D365 Not allowing any type other then fixed amount

We are working in AX D365 with Retail. We are entering orders into the system and we want to add on additional charges with charge codes. Also, with using charge codes we can have a fixed amount but also the charge can be a percentage of the total order. Fixed charges appear to work fine but percentages are an issue. Everytime I enter one I am getting the following error message:

Non-fixed charges are not allowed on sales orders from POS

Any thoughts onto why this maybe? It worked in AX 2012.
