I see that the song is still available for purchase on the website. How is this so? I thought I purchased the rights to this beat?

Hi, yes you've purchased rights to your beat giving you Unlimited Rights.   There's an option when you click "buy" to "hide from others".. if you didn't select it at first, you can upgrade your order after the fact at https://sfrbeats.com/orders   This will remove the beat from the website preventing others from purchasing right to the same beat.  See the screenshots below:
