According to SI convention, the kelvin is never referred to nor written as a degree. The word “kelvin” is not capitalized when used as a unit. It may be in plural form as appropriate (for example, “it is 283 kelvins outside”, as for “it is 50 degrees Fahrenheit” and “10 degrees Celsius”).[5][63][64][65] The unit’s symbol K is a capital letter,[39] per the SI convention to capitalize symbols of units derived from the name of a person.[66] It is common convention to capitalize Kelvin when referring to Lord Kelvin[5] or the Kelvin scale.[67]

    According to Wikipedia it was officially changed from “degrees Kelvin” to “kelvins” in 1967, so it’s possible you were seeing the change ripple out as they were made. I wonder how long it takes for decisions like that to get from a decision announcement from the CGPM to an update in textbooks that students use. Probably varies by income level.
