I'm using your plugin with a custom format that displays the document title (%TITLE%). Everything works fine if I use activate auto shortcode; however, if I use the manual shortcode with size=custom the filename is being shown instead of the title. For example, with a document as follows:
filename.pdf - A test document
with auto shortcode I get something like this:
A test document [icon] [size]
whereas with manual shortcode I get:
filename.pdf [icon] [size]
Is this a known problem (I didn't find anything about it)?
