It’s highlighting the syntax issue(s).
Also, read your code from the bottom, upwards. That way, your brain will read it differently and you’ll be able to spot where the error occurs.

You may be missing an <aside> somewhere earlier.

I checked and everything was in place 
you have a <ol>
do you also have an </ol> ?
The ol element is inside the aside element, so it may give a warning if you didn’t end the ol element before the aside element ends.
