Question A section of interactive in-build tutorial somehow not working

I have successfully completed another part of default Unity tutorial. To be more preciously: "Microgame Platformer", and it is fine looks in the internet browser program, but in Unity Editor, one section ("Microgame Mods") is still not shows as completed. In the process of me working with tutorial, I have updated Unity Editor few time, maybe it is the cause? But it only affected those single section, for an example "Build and publish" successfully completed after the update.
