While Tersus is constantly evolving and changing, it is our policy is to keep the tutorials (and other documentation) in sync with the most recent stable version (which at present is 1.3.59 - see the Download page), and releasing the aforementioned changes as latest (1.4.4 at present).
One of the major changes since the last stable version is in the way the rich table is implemented, and we will need to update that tutorial to reflect those changes.
We think that while learning Tersus, it is a good idea to use the stable version, to avoid problems such as those you've encountered.
Is there any specific reason you're using the latest version? If not, I suggest you revert to that version.
