ert test fails for org-journal

I'm learning how ert works. org-journal has an ert test suite.

When I run the test suite, there is a single failure out of 10 tests.

I have a fix for this, but wanted to verify that others see this error, since I'm unfamiliar with the tool.

To run the tests, I am executing this from the command line in the org-journal directory:

emacs -batch -l ert -l org-journal.el -l tests/org-journal-test.el -f ert-run-tests-batch-and-exit

Full output from the batch command:
