New spread in document causes all text frames after the new page to move toward
I have a very strange issue with my indesign file. If I create a new page, all text frames in all subsequent pages (not prior pages though) move left or right (depending on left or right spread) toward the spine 1". If I create a second page so that all spreads were in their original order, then the text frames go back to their locked position. Please help. Has anyone experienced this before? I have attached two images showing the problem. The first screenshot shows everything as it should be. In the second screenshot I have added a spread above these pages and all the text frames have moved inward.
