Documents not showing up in LOCAL section of android app

I have pretty much the same problem - though I do have some documents showing (downloads etc), I can't get the local tab to show the documents I have stored on my SD card (which is all of the ones I actually want to use). One way to get to them is via the floating station but it then asks if you want to create a local copy which entirely defeats the purpose of having them on external storage rather than clogging up internal storage; and the other method is to go to the SD card directly in the main phone Settings but that is too long-winded to be doing every time you need to open a PDF...hopefully they fix this soon otherwise I will be looking for another PDF reader...

See if the following forum post is of help to you:
