No. You are not missing anything. These checkboxes fill in parameters 
that are passed to the
stylesheet. The point of these parameters was to reduce/eliminate the 
need for other stylesheets
beyond simple.xsl. At this time, only simple.xsl uses the parameters.

This is good news as a repeatable, isolated bug can be fixed.

I have further isolated the bug:
After bringing up the application with cutandpaste.xsl, I switched to 
Louis Segond (FreLSG) and back to simple.xsl.
No problems what so ever. This bible has no Strongs, Notes, or cross 
references.
I then turned off all options and switched back to a bible with Strongs, 
Notes and Cross Refs. And I gradually
turned on the options. The problem is somewhere in Notes.

I just remembered that we have the ability to override resources in the 
jar with ones in ~/.jsword.
If you extract xsl/cswing/*.xsl from bibledesktop.jar to ~/.jsword, 
these files will be used by BibleDesktop.
By commenting out parts of the stylesheet we can isolate the problem.
Also, BibleDesktop (actually JSword) will reload the stylesheet on use, 
if it changes. So it is not necessary to
restart BibleDesktop between changes, it is only necessary to switch 
Bibles.

I am getting a different error and it may be due to the fact that I am 
offline right now:
