What model switch? 220-8? If yes I feel like that's always been that way from what I recall.

I checked and there was actually a bug on that all the way back in 2016.

It is..., maybe I'd never plugged in a GBIC without a cable before. I only did it this time to show someone else on the community what they should see when a GBIC was plugged in!
