Duplicate scores

Not sure what I did but I have 2 scores coming up on the page, one on top of the other but the second one slightly lower than the original one. There is a gray bar going through the middle horizontally. The title is off to the left side in a gray tab with an "X" to the right of it for both scores as well as on the score. I can click out of them by clicking on the "X" but every time that I try to bring up a piece, they are always with two scores now. Can anyone give me a step by step way of fixing the problem? Do not know what I clicked on to get this.
