The last question in the Computer Basics section seems skipped

Not sure about this, but I just saw the last question and it immediately moved to another page.

Environment: Google Chrome 66.0.3359.181 (Official Build) (64-bit) on Ubuntu 16.04
Adblock Plus installed but disabled on this page.

Hope it helps.

Please submit bugs as GitHub Issues. Thanks for your help.

Thanks for replying.
After a close look as I finish all the questions, I think the last question shown always belongs to the following section.
Guess this is a feature. XD
