There has been a recent change to ZBrush that will cause the program to act differently than the videos in the course. If you have already downloaded and installed version 2021.6 or later, take a moment to make a change to one of the Preferences.

Here shortly, we'll be installing the custom interface, so we'll work more with setting preferences.
