CMB contract test failure

Hi all, it looks like [SMTK’s master branch](https://open.cdash.org/index.php?project=SMTK] has developed a test failure: the CMB contract test fails due to a broken OscillatorSingle test. The OscillatorSingle test passes on CMB’s dashboard. Any ideas?

SMTK is still on an old CI bundle. I expect https://gitlab.kitware.com/cmb/smtk/-/merge_requests/2395 to fix this. @aron.helser
