SetaSilk Woes

Does anyone know why it's foxing? It would appear that the pigment and the binder are seperating. I've shaken the bottle, and shake it periodically while using but it's still doing creating this fox or ghost like image that I don't want. The fabric is silk charmuse and is stretched on a frame. The part that really bites is this is on my final fabric piece, the paint didn't do this on any of the test fabrics.
