When a drop down field which has "--None--" as the value saved, is also read-only, it shows as blank.
The same field when not read-only, shows the "--None--" option fine.

Steps to Reproduce

1. Navigate to https://<instance>.service-now.com/nav_to.do?uri=/change_request_list.do
2. Filter the Change requests with "Conflict Status" equal to "--None--". 
3. Open any Change from the list.
4. View the "Conflict Status" field. It shows as blank since the value set is "--None--".
5. To test the field in non read-only mode, go to the "Conflict Status" field's dictionary and uncheck the "Read only" flag and save.
6. Reload/open the previously open Change record.
7. You can now see the "--None--" option displayed.


Currently, there is no workaround.
