That’s all I can think of and the only thing I can remember that will cause an ACF field to be disconnected from a term when it is edited, or a post to become disconnected from a term. However, there is no end to the way filters and actions could be also effecting it, but this is probably where I’d start, first carefully looking at the term ID values and the term/taxonomy relationships. Maybe these categories are older that you think they are.
What happens to the values selected for the business type and subcategory when you edit one of the types or subcategories associated with a post?
