Hi @mattbeck
Are you able to check the DB wp_posts
table for any rows where the post_excerpt
cell contains the field’s name (main_title, etc)?
Do any field rows exist? You can also try searching for rows where the post_type = ‘acf-field’.
If you find any rows, perhaps consider deleting these to remove the duplicates.
If no rows are found, the duplicated fields must exist somewhere else. Please search your websites files for the field name / field key and see where it pops up. Perhaps there is another json file?
