Drum Machine Last Test Not Passing

I can’t tell if it’s a problem with my code or if it’s a testing bug. Some feedback would be greatly appreciated.

my codepen

**7. When a .drum-pad is triggered, a string describing the associated audio clip is displayed as the inner text of the #display element (each string must be unique).

Error: Each time a drum pad is triggered, a unique string should be displayed in the element with the id “display”

Great to see your project is passing all the test now.
