Xray icon not showing

I had a student the other day where their Xray mode Icon in view/styles was not showing on a PC. It only had back edges through monochrome.

Not sure why this is happening?

There’s an obvious explanation for the X-Ray icon’s disappeared.

There’s an easy way to put it back in its default location.
