Playlist messed up track order by hitting one button.

Hello!

I have recently been using rekordbox for mixing and I have come across a small mistake that is a huge problem.

When creating a playlist right in the software, I simply dragged and dropped in the order which I wanted my songs to play, but I have hit the bpm button at the top of the column and has now rearranged my order and I can not "unselect" any of the column titles.

Can you get the order of the playlist back to where it was?

Thanks,

 Cory
