Why Does My Image Glow Change to Grey in Overprint Preview?

[Jessica29882442d4g2]

Hi there! I'm creating some assets for print at the moment - but for some reason, when I switch to Overprint preview, the glow in my TIFF image switches to an ugly grey glow. Screenshots attached but unfortunately I can't show much due to confidentiality. My overprints are also turned off.

Any advice is appreciated - thank you in advance!!

Also, are any of the colors in your capture Spot Colors? Make sure all of the color is process.
