Describe the bug

In some cases during migration, users core_store gets corrupted causing an inability to view collection types in the content manager. This currently only occurred for a collection type and not a single type.

Steps to reproduce the behavior

This occurred during a user's routine migration process. To our knowledge, there aren't any steps outside of what we prescribe in our guides that the users followed.

Screenshots

• Pre-migration
  

• Pos-migration
  

Additional context

To get past this, the user had to delete their core_store content manager config

This should be fixed in #106 but I'll run some additional tests to confirm
