At the moment the plugin cannot retrieve the build description from jobs within folders.

Fix: use getItemByFullName instead of getItem in the StatsHelper class (2 occurrences - but findBuildCause will not be used at all)

Job j = (Job)(inst.getItemByFullName(jobName));

Tested with jobs within and not within folders and both cases are working with the changes.

May one of the maintainers can update the plugin.
