1) Create a new Custom Field for "Documents Folder" with the name "Display Name" and type should be "Localized Text".
2) Now go to "Documents and Media" and create a new folder and provide values in custom field "Display Name"
3) Click on save.
4) Now edit the newly created folder.
Results: The value corresponding to the custom field will be lost which was provided earlier.
Expected behavior: The data in the custom field shouldn't be lost.
