Drum Machine Project: I fulfill all user stories but 4,5 and 6 fail

HTML-CSS
1

I built the Drum Machine using React and so far everything the user stories request is active, yet tests 4,5 and 6 are failing. Is there any specific way we have to do particular parts of it? One thing I think may be the problem is I use the .map() method to iterate a “drum pad” component 9 times rather than having 9 hard coded instances of it. Could that be the problem? Here’s a codepen of my project so far.

You missed this part:

a class name of “clip”
