Can't email calculated columns

When emailing columns to students, those that are calculations come up blank on the PDF that is created in the email.

I'm assuming this is a bug?

Hi Daniel,
If you've just created that calculation column, you may have to switch tabs before sending the report.
Select another tab in that same grade book, and switch back to original tab. The result will then appear in that PDF. It is a bug we missed in this release.
