When I enter an address in Contact Entry, the Suburb autocomplete is spelled incorrectly. To fix this, find and correct all incorrect spellings within the database.
In Contacts > Status, deselect all selected status filters. This will reveal all contact records regardless of their status.
If necessary, use the column options tool to show the Address 2 (Suburb) column.
Open the Column filter for Address 2. Locate and select the incorrect suburb spelling to show records. Correct the spelling for each record.
This guidance applies to other auto-correct fields such as Listing Entry address fields.
