I am using a fresh install of DNN 9.1.1 for a new website. Every time I edit and save a top-level page, that page moves all the way to the right. For example, If I have 3 pages, Home, About, and Contact, if I edit Home, then click Save, the order of the pages changes to About, Contact, Home.

This is extremely frustrating. It's difficult enough to handle this in development. Once this site goes into production, I will have to remember to re-order top-level pages every time I save them.
