I created a CPT "landscape design". I created a custom field group assigned to that CPT. I use the Post Title, Post Decription, and Featured Image
Custom Field Group:
Before Image
After Image
Image Gallery
Upon save all the fields vanish. The title does show in the CPT list. I have deactivated all plugins, changed themes, enabled debug, and have no information to go by as I have set debug to true. I get no information. https://www.loom.com/share/fad6b07573b04195a224f93eda7814e6
