Unable to select kdbx or kdb from Google Drive app

What steps will reproduce the problem?
1. Select the Open from option in KeePassDroid 
2. Navigate to kdb or kdbx within Google Drive (as in select the Drive option 
in the panel on the left hand side
3. The kdb and kdbx file(s) are grayed out and thus can not be selected.

What is the expected output? What do you see instead?
I would expect to be able to select both of these files, and successfully load 
the database.

What version of the product are you using? On what operating system?
KeePassDroid v1.99.11
Android 4.4.4

Please provide any additional information below.
Occurs with any kdb or kdbx file I've made. I have only made them on a Win7 x64 
machine using KeePass v2.28 (using the professional edition installer 
downloaded from http://keepass.info/download.html)
