Confirming. Reproduced this issue.

JSON is present in DB and is returned with GET request, but it is not displayed in the field.

DB:

GET request with findOne from Admin (/content-manager/collection-types/application::articles.articles/3):

Getting the same issues here:

• JSON field, can't see it in the field, but it's in the database
• Date field, can't see it in the field, but it's in the database
• Slug field, getting re-autogenerated into name of the collection
• Toast UI plugin Richtext, can't see it in the field, but it's in the database (I had to remove this plugin for now as this is the biggest issue, imo). The normal Richtext editor works fine.

These are all just view layer issues it seems, the data itself is fine and saved properly.
