Unfortunately, I am unable to reply to the original thread but, yes, you're right, The Bluebell is a bit of a mess. I did try to correct things with some location reallocations, but to no avail. Your explanation does make sense though.

The pub needs to be removed from Norwich Postal area and added to North Walsham. Then apply "North Walsham Town" area. Once done, the region "North Walsham Town" needs to be unlinked from Norwich (it seems to be linked also to North Walsham, as you'd expect).

If deletion and recreating is the best way forward, then I'll repost the photos.

Good luck with all that!
