RX 570 showed VDDCI Values (usually it doesn't)

Might be more of a "Bugreport". Today i started HWINFO and usually it doesn't show VDDCI Values (they also do not appear in the Options to enable) however this time it showed some "odd" values (i think it was 0.0012v) which were displayed in a bright-grey color (that's also why i noticed it). After restarting HWInfo the Values disappeared. I think it might be related due the fact that i started HWINFO during a game. but i still wonder where it got that "value" from?
