Read only fields for interviewing
I found out the issue. The reason that some of them were read only and some weren't was due to a bad import. It seems like the Contacts that were having those issues, had more than 1 empty Supplementary Addresses. There would be 1 Main Address with it geocoded and filled in, but there would be like 4 empty address entries. Removing all the invalid supplementary addresses fixed the issue. Not too sure why those addresses would mess up the results but hey, at least it got fixed!
