I'm assuming from your post that their address is correct but the pin is in the wrong location for their address. One thing to check - if they are in a new neighborhood, the address may not yet be recorded in whatever service the church uses to place the address pin. I have seen that before and when the software errs in automatic placement, it seems to drop the pin in unpredictable locations. In past experience, Bing maps seemed to update sooner than Google maps for new neighborhoods and homes being built in our area (as much as a year sooner). The member can move their pin to the correct location on the Church Directory and Map, or the clerk can, to get it in the correct location.
