Are the problems you are using in one of the public libraries, or are they locally designed? If they are part of one of the public libraries, you should report the ones that are missing this value where you think it should be set to 1. If they are locally created, you should ask the authors to update them.
They are part of the public libraries. I see that these issues can be reported to Bugzilla.
I added the line to course.conf, and this seems to do the trick.
Thanks again for your help! You completely resolved my issue.
