Hello!
I have exactly the same problem as you, my project was in Strapi 3 and I migrated to Strapi 4.
I noticed a certain pattern. It seems that the “old” content-types (created in strapi 3) are the ones that reset, and all the “new” content-types (created in strapi 4) remain bug-free.
In the next few weeks I will calmly analyze the functioning of this table in relation to the strapi code to find this error… because as I work with large data (consequently large form) and we have 1-2 deployments every week, it is unfeasible to have to always redo it in Hand this part.
By the way, thanks for citing this table,
I always racked my brains to find where strapi saved the organization of the form hahaha
