Address layout modification

SuiteCRM 8.1.3 on MAMP with PHP7.4.21

OK, so having resolved the postalcode move to after city in ‘Grouped Addresses’ , the next step I’d like to achieve is adding a ‘Suburb’ field/line between street and city for all grouped addresses, because that’s what we use down here in this part of the world.

So I thought I’d start with just the billing address in the Accounts Module. I followed much of Add district into address by cloudcon.
Also added in ‘suburb’ in the grouped_fields_type_map.yaml. Did all the usual Admin → Repair → Quick Repair and Rebuilds. Made sure the cache was deleted.

Result:
I have the the extra field in the database, I can show it in listview of Accounts, but (after a full day of tinkering) I cannot get it to show in the Billings grouped address on Accounts. Not in Detail View or Edit View.

I would really appreciate any help here please.

Regards
Terry

Maybe this should be a new topic???
