Piggly Wiggly review: Returned check that was paid

I have an issue with a check that was listed as unpaid on my credit report from Feb 11, 2018. This occurred at the Plymouth Piggly Wiggle store in Wisconsin. It came from The Stark Collection Age. I have paid this amount. It needs to be removed from my credit. I am trying to sell my home and am unable to because of your neglect to remove this from my credit report.
