Hi @tazintosh
This behavior is used for all of the fields as default. Imagine you have a text field, and then you decided to change it to a post object field (which is saved as ID in the database). Because post object needs the ID to get the post but the database still has the text from the text field before, the post retrieval will be failed.
Now imagine if the post object field shows the text instead of empty while the other post object fields show the post title, it sure will cause confusion because you won’t know which one has the correct value.
But if you think the default behavior should be showing the value in the database, you can always open a new ticket and submit a feature request. You can open a new ticket here: https://support.advancedcustomfields.com/new-ticket.
Hope this helps 🙂
