I like to purchase a tutorial, I couldn't identify what is the version of this tutorial from Illustrator CC title. Are you able to say the version?
I use latest version. Some times above version may be incompatible for new learners.

Click the Illustrator CC that you have highlighted, and choose About Illustrator CC.
It is a screenshot of a demo video, you can't do like that here.
This is a paid tutorial but preview is available to see. I do not have link in my hand, as no one was answered positively I forgot the tutorial. If I came across again I will post it.
I use latest version of Ai. Some times older version command and newer version command mismatch. That was why I have to confirm before buying.
the tutorial mentions the Properties panel was new to that version so it must be CC2018.
You should be able to follow if you're on a newer Illustrator version
