The Code Completion Learn feature on PyCharm CE

I am following the Code Completion example in the Learn feature of PyCharm CE;

PyCharm 2024.1.4 (Community Edition)
Build #PC-241.18034.82, built on June 24, 2024

and I am following the Basic Completion example as follows which says;

“ default, PyCharm proposes completion for your code instantly. Start typing ‘director’ right where the caret and you will see the completion list with matching suggestions.”

I do as it says and start typing ‘director’. I can see the pop-up with code completion suggestions but after I finish typing ‘director’ nothing else happens. I try typing the return key but PyCharm does not take me to the next step in the example which I can read greyed-out. It just says 'unexpected sample modification Restore.
