We have two field groups (1. Blog, 2. Training) created in custom fields. Data for Training field group is not loading on the post page whereas Blog fields are loaded fine.
Fields contain simple field type like textarea, checkbox_list and image_advanced. Blog field group has 3 fields with one of each field type and Training has 3 checkbox_list instead of one.

We have checked the database and it seems the data is already there in "wp_postmeta" table.
If we go back to older backup of database (before May 2023) the fields are loaded fine for training metabox, but somehow it doesn't work now.

We compared the settings for each field types and they are identical between the working backup and now. Can you please help us resolve this issue?
