Sorry about that, I did not notice the response in there. When I review the line item info in the request it looks like this:
The values seem to match what is expected but the description seems like it might be off. What happens if you have the description for the item without any <p> tags or * in it? If you continue to have this problem after adjusting the description let us know and I will get a ticket opened for you so we can help you get to the bottom of this.
