Bug in Smartsheet University Designing A Project Sheet course?

I don't know where else to report this or ask the question.

Currently going through the Designing a Project Sheet course on Smartsheet University.

Activity 4 asks you to change line 7 duration to 0 (zero) in order to change that task to a milestone.

However, this is not functioning as explained or as expected, nor as it does in my actual, real project sheets.

The task when converted to 0 duration should show as a milestone.

This is not happening.
