Midi Files Showing Up Blank in Media Bay

I wonder if anyone else is having this issue with the Media Bay?

If I scan for something with all file types then I get the results as expected, but of course this tends to be a huge list.

If I ask it for midi files or loops only, the information line goes blank so that there is no information on the results of the search.
Bizarrely I can preview them and drag them to the project however this can be a bit of a random chore.

The mini media browser works as it should but of course does not offer as flexible a workflow.

Hardly the end of the world but would be nice to know if this is unique to me or something others are experiencing.
