The yellow bar that changes the bars in the track and determines the length of the song is stuck. I extended it to the right, then it disappeared. I found it at the beginning of the track scrunched up, which I'm pretty sure it's not supposed to be able to do that. I can't move it at all and can't select a certain point of time to listen to my track because it will always start playing at the beginning. Here's a screen recording I took. - https://imgur.com/a/i6B01gi

Forgive any ignorance of mine; in advance, thanks for the help.
