As it is now, deleted ACF fields stay in the database, which can sum up on larger sites with a bunch of ACF fields. It would be great and very helpful, if there was an EASY NATIVE way with ACF PRO plugin to being able to delete old or unused ACF fields right inside the plugin from the database, without the need to delete them manually from the database. Besides the mess unused fields leave in the database - in some pagebuilders (e.g. Bricks), deleted ACF fields still stay in the pulldown selection choices when connecting content elements with ACF fields, which - again - messes up the pulldown-lists and makes editing and working with ACF fields quite hard sometimes.
