WHY??? This bugs the crap out of me. It always has my work info by default when paying with Apple Pay in all my apps - Apple Store, Groupon, Panera, etc. Everything is correctly set to my home info in Passbook & Apple Pay settings, so why does every app want to pull my office info?
Did you actually click on "home" and verified that it's the correct address? I have several addresses under home and checked the correct one for it to link to.
