Thanks @hube2 for your response. Your solution of using the clone field to bring the fields into the flexible layouts works great!
My problem now is that I have over 500 live pages which use the old, bloated flexible layout field. I can rebuild them using the clone fields method but how do I get the data from the old field into the new one so I don’t have to rebuild and repopulate the whole site? Any shortcuts or tips?
Thanks for any help anyone can offer!
The issue is when I am editing and saving changes to the field group in the wp-admin. Since it has 90+ layouts each with several fields, it takes forever to load in the browser and is very difficult to make any changes to.
