Why does Fiverr automatically markup custom milestone offers?

Hey everyone!

Hope you're doing well:) I'm pretty new to Fiverr and I'm trying to send my first custom offer with milestones. I write the milestones with their specifications and set the price to 400 CAD. As soon as I send the offer, each milestone goes up in price to 560 CAD which was not the price I agreed on with my client. Why is this and how do I fix it?
