Corrupt Raw or Jpeg files on qxd Card only

I purchased a D500 this year and while on several shoots I would have an occasional corrupted file when I downloaded it into light room. Now what I'm calling a corrupted file is this. The picture was taken and recorded on the QXD card and when imported into Lr. Some photos have 1/2 the photo and the bottom part of the picture are discolored lines going from left to right. in the beginning it happened on occasion but over time it got worse. I validate the Sandisk card did not have these files corrupted, and when I changed out the QXD with a different brand card the same thing happened. Sent the camera in and Nikon changed the Memory compression. Don't know what that is. any one hear or have this problem? oh my firmware was update when I sent it to Nikon
