How do I remove the annoying gray arrows that prevent the entire audio from being played?

[Njjeppson]

This gray arrow prevents me from being able to play back my audio from the beginning to the end, and there seems to be no way to get rid of it. It’s just always there, no matter what I do, and it makes working with Audacity impossible. How do I remove it?
