Much like John Elion above, when I make a clone of the affected job, the cloned job has the same issue as the original job. If I create an entirely new job, and fill in the configuration values manually, the new job works fine. Somehow, the cloned job is "inheriting" the buggy behavior from its parent. My jobs are the FreeStyle type, and they use the Build Parameters configuration option. On my Jenkins installation, I use the Git plug-in, the Git Client plug-in, and the GitLab plug-in. The Jenkins master and all of the Jenkins slaves run Ubuntu Linux. So far, the only solution to this issue I can find is to manually re-create the affected job (no cloning).
