Extra column that cannot be edited is shown in Property Matrix when editing a Data Asset

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.

1. Create a new Blank Blueprint project.
2. Add a new Data Asset to the project.
3. Select any Data Asset Class to associate with the new Data Asset
   • Any class should provide the same result. Tested with AutomationViewSettings and TireConfig
4. Right-click on the new Data Asset.
5. Select Asset Actions -> Bulk Edit via Property Matrix.

RESULT:
The Property Matrix window shows a blank column named "Native Class" that cannot be modified.

EXPECTED:
There is no "Native Class" column.
