I'm stuck and need help.

Under File > Document Properties. I need units to be displayed inches. Whenever I make the change, and save it, it's back to mm when I reopen the document.

I've made the changes and saved it under the templates folder. It saves details like border settings, page orientation, but it won't save unit settings.

This just started happening once I upgraded to .47 - I print alot from Inkscape, my printer reads in inches, so the mm setting is throwing my printer off.

Any help is greatly appreciated.

Are you sure you're changing the default units for the entire document, in the top right corner of Document properties, not the ones in the middle next to page size?
