i am also unable to see any tracks or waypoints anymore. I can create and store maps in oruxmaps and directories in the tracklog database.
When i try to import any kml i get an error "can't load data".
In the waypoint or track manage menu i can see the created folders but no other data in it.
The timestamp of the oruxmaps/tracklogs/oruxmapstracks.db file is created/updated after running oruxmaps so it seems to be writable for the app.
I'm using Android 4.4.4 without external memory.
