Been like that for a while for me too but I couldn't find any posts regarding this. But now since 1.17 update I can't change the color of the calipers from lime green. I've seen a post regarding this issue.
Yeah, it's like that for all of us. Thought it's likely a problem that'll fix itself once PD repairs it. Just set the color you actually want and at some point that one should appear again. With styles and liveries updating themselves constantly stuff like this won't cause any issues to shared stuff, just like the wing endplates on the F1500T-A that were broken until recently but no liveries need re-sharing just to get that error fixed on already shared styles.
