When using the Property Matrix to edit a Data Asset, there is an extra column shown named "Native Class" that cannot be edited. This is most likely due to the code only checking to see if a property has the CPF_AssetRegistrySearchable flag. Including an additional check for the CPF_Edit flag removes this extra column.
The Property Matrix window shows a blank column named "Native Class" that cannot be modified.
There is no "Native Class" column.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-67811 in the post.
