Problem with button colour states

Hello, I'm having trouble with changing colours in my button states. Every time I add an over or down keyframe and alter the colour and font weight it changes all the other frames to match. I thought maybe it's a symbol thingso I drew a shape and tried again without converting them, that didn't help. Then I tried cnverting the elements to symbols, still doesn't help. I've follwed tutorial steps and it worked previously but when had to edit the button and it just went super buggy. On a today deadline and new to Animate CC so I'll be very grateful for any idea of what I'm missing here.
