Weird echo capturing on audio track

I just moved the hat sound from midi to audio, and in the audio track playback, I’m hearing this echo that’s not supposed to be there. And also there are these multiple dotted lines (vertical) that I’m visually seeing in the audio track as well. Can anyone please help me with this? It’s quite fraustrating.

What exactly is this picture of? Did you create a stereo event of the hi-hat? The dotted lines you speak of do not show up, BTW.

If this is a stereo recording, then the echo you are hearing could be that of the two images that are not in sync.
