Ok, great! So back to my original response: you have five master pages in your document (the last one is blank so you don't need to worry about it.)
When you use Format > Page Layout > Column Layout to set the margins, FrameMaker only updates the default masters. Start there anyway and change the inside margin to 1" and the outside to 0.6". This updates the default Left and Right masters.
Next, you will need to go to View > Master Pages and manually update the two custom master pages used on opening pages of a section so that they match the updated default Left and Right masters.

- Control+click on the template frame (the large frame in the middle of the page) and choose Graphics > Object Properties > Dimensions:
Left offset to 0.6"
- Control+click the footer frame. Graphics > Object Properties > Dimensions:
Top Offset: 7.889"
Left offset to 0.6"
firstR
- Control+click on the template frame. Graphics > Object Properties > Dimensions:
Left offset to 1.0"
- Control+click the footer frame. Graphics > Object Properties > Dimensions:
Top Offset: 7.889"
Left offset to 1.0"
This will standardize the margins across one file. You can repeat this in the other chapters, or use File > Import > Formats and import just the Page Layouts from one file to the others (uncheck the other options).
