Anchoring Mathcad Prime 1.0

I've got a 15 page document in Mathcad Prime 1.0. Items are strategically placed on the pages for readability and page breaks. However, when I save, close, and reload the file, my math and text regions seem to have all moved around; creating overlapping text regions and regions that flow over the page breaks.

Anyone else seen this problem or have a tip on how to anchor these regions to the page between file opens?
