Thanks for confirming that your publication formats are ordered this way. It looks like the publication formats appear on the website in the order that they were added in Production. So you should add them in the order that you want them to appear on the website.
I don’t know of a way to change the order after they have been added other than to delete a format and add it again (although that could interfere with any statistics that have accumulated). You could submit a feature request on Github to be able to re-order the formats by dragging and dropping them, or you may have another idea of how it could work.
