Steve,
Let's talk about what you are trying to do, because I'm not seeing an issue with your file. All of the annotations on the first page of your file are not saved in MobileSheets - they are saved in the PDF itself. That means you can't edit those annotations by default. If you need to edit those annotations, you can go into the annotation settings and enable "Allow editing of embedded PDF annotations" which will let you interact with those annotations and move/delete them. I would not recommend leaving that setting on if you don't need to edit embedded annotations though as it will make the loading/saving of annotations slower as the file has to be reloaded in a writable state in order to save the modified annotations.
