Missing Title and Caption

I downloaded and installed the plugin. It worked for me with a test photo. I then added meta data to my photos in Lightroom, exported them and uploaded to WP media library. However, the title and caption were missing. I have check the settings in the plugin, and they all seem to be correct. The IPTC data is in the file. I uninstalled the plugin and reinstalled. But I am getting the same problem. The Title is blank – it is not even filled in with the default of the file name. Not sure where to go from here. Any help wold be much appreciated!
