This bug (which gives false warning messages) has been fixed. The bug occurred when two courses such as "foo" and "foo_bar" existed and the tables for the "foo" course were checked by a routine in CourseIntegrityCheck.pm. The routine thought tables for the "foo_bar" course belonged to the "foo" course and this resulted in the warning messages.
To fix this bug (which is annoying but doesn't cause problems) you can download the rel-2-4-patches version of CourseIntegrityCheck.pm which resides in the /opt//webwork/webwork2/lib/WeBWorK/Utils directory.
I removed the brief notes Xiong added to the Course Administration page on the wiki. Thanks Xiong for added those but they are no longer needed (at least if people have a current version of WeBWorK).
