Docker lab issue in beginner course

I was going thruough the docker beginner course in the lab it is keeping asking about the images and containers how may are installed …When i ru the commands it does not show anything …

Whatever I answer obviously is going to be wrong because it is checking something …Dockers does not have anything installed…

Although in the second quiz it said it installed some containers but did not install anything when run the commands…

Hope you fix it …I am concerned the course going forward as Spending lot of time

Could you please share some more feedback on this, like name of the specific lab, what error it throws, if any?
A screenshot could help a lot.

I just tried it and it worked fine on my end.
It could be transient issue.
Could you please try that again?
