Illustrator automatically changing Color Hex from Library + Swatches - CMYK

Illustrator is automatically changing the colour hex's on CMYK documents. This is from when the document is created from scratch. I've checked the color settings, there are no imported images affecting it. When I click off of the colour selected it automatically changes without me requesting it to.

Looks to be a bug? I've restarted the program to no avail and I've attached a video to show the issue I'm experiencing in real time.
