Camera Recording JPEG Randomly

[gradynichols]

Hi. I shoot with a Canon 5D Mark IV. I shoot RAW to a compact flash and JPEG as a backup to the SD card. Today I noticed that on my RAW Compact Flash around 20 of my files randomly recorded in JPEG format on the RAW card. The files are completely random. Any clues as to what causes this?

Thanks for the help
