Hi @sbrenner7
Can you please confirm that the data is saved as “3” in the DB for the wp_postmeta row where meta_key = ‘user_id’?
I have a feeling that becuase you originally had the field as a multi-select field, the data is saved as a serialized array.
Please change the user field to a single select and resave the posts to update the values in the DB
Thanks
