This is different from my experience. I have never had to enter my address. It has always been there ever since if first created an account years ago and long before the site started using the LDS Account log on. The only address that was added has been the bishop's and that was added by the system some time after the site converted to using the LDS Account log on. Prior to that all unit materials orders had only one address available for shipping. It was the bishop's home address.
I was surprised to see that sometime within the past year that there was an option to select a shipping address. I noticed that my home address had been included as an option. But I never tried that option for unit materials orders since I presumed it was a programming bug. For years the only place a unit materials order could be shipped to was the bishop's home address. It was the only address registered, or associated, with the unit. I still am not certain using my home address will, or will not, create problems for a unit materials order.

to sign in to the store and check my account settings. I saw both addresses, mine and the Bishop's, but
neither was marked as default.
OK, that sounds like good support for your theory as to why orders do not complete. But how that situation is created is going to be hard to track down.
I tried to find a way to duplicate the situation you described where neither the unit address (actually the bishop's address) nor my home address were set as the default address. I could not make that happen. The unit address is not editable since it is created from Church records so I could not delete it. I also could not delete my home address. When the address fields were deleted the system required information in the address fields for me to save the changes. The only way to make my home address not the default was to make the unit address the default and likewise for the unit address.
