Hi - I've realized finally why my data is getting lost on the admin screen. I recently needed to solve a problem of selecting between different taxonomy children with the same name, and since I was setup with taxonomy custom field type Select Advanced, I decided to try switching to Select tree to see if it would alleviate my issue (it did, but couldn't figure out to add more/clones, but that's a separate issue). BUT, when I saved my post from the new metabox custom field settings, all the info disappeared from the post on the admin side, and I haven't been able to figure out how to get it back. The data is still in the db, and available on the front-end, but now I can't edit anything...not good result as you can deduce.
Can you reproduce?
Using AIO.
Thank you,
Sam
