Problem: Binder is not consistently displaying characterization metadata

[sromkey]

To reproduce:

Upload a DIP from Archivematica to Binder, then view the files by clicking on files in the file list, from the context browser view. This is also possible from an AIP view page.

Expected result: when original files are clicked on, it should display Characterization, Format and MediaInfo metadata. When a preservation derivative is clicked on, it should display Characterization and Format metadata (MediaInfo is not run on preservation derivatives.

Current behaviour: It's mixed. Sometimes it appears to work as expected and other times not. For an example in our test environment that is working as expected (for the original files) see: http://binder-atom.archivematica.org/drmc/aips/5d5ecd01-a15a-4365-9d50-fccba0b030ea

For an example that is not working as expected see: http://binder-atom.archivematica.org/drmc/aips/e689e1e3-740d-4176-857c-1cce6aca4625

Additional context: I did double check the METS file to make sure that the MediaInfo metadata exists and it does.
