paint washing off stove knobs

[Shorebird]

I had frying chicken spatter last night. I had to wash the range top and knob area. Pretty normal, right? I was shocked to have the word "OFF" wash right off one knob and smear on a second. I can live with that because I know the off position but what if it also washes off the heat control for the oven temperature? Our's is a Suburban range/oven combo with the folding glass top. 2016 model Rockwood. Anyone have to ask manufacturer for a replacement knob?

Same thing happened on my 2504s, i touched the knob to light the burner and the word off literally came off in my hand.
