It's been like this for me for about a week, when I contacted the help desk about this. I'm surprised it is only being noticed now.

Dear Trader
Please be informed that the status of native Stop and native
Stop Limit orders are currently being displayed in dark blue
rather than green. However these orders are live at the
exchange.
