Looking at the debug log it seems that chapter numbers or verse numbers or bible number is missing.
Look at the this example from KJV:
<BIBLEBOOK bnumber="1" bname="Genesis" bsname="Gen">
<CHAPTER cnumber="1">
<VERS vnumber="1">In the beginning God created the heaven and the earth.</VERS>
<VERS vnumber="2">And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.</VERS>
OpenLP requires the BIBLEBOOK attribute bnumber, the CHAPTER attribute cnumber and the VERS attribute vnumber.
