Browse to media plate not working

Hi,

If I drag an img media source into my level an MI_MediaPlate material is instantly created. I am able to grade the Media Plate texture with great results. However if i click ‘Browse to MI_Mediaplate’ under it’s material slot in the details panel, to access the source material in the content browser, this simply leads me to the main level into which it was created, not to the actual material. No actual material is selected. Is this a bug?

How do i access the mediaplate source file in the content browser?

Do I have to expose the media plates plugin folder etc to the content browser? In which case how?

Thanks in advance.
