problem with lip sync and thin black outlin when exported

I am working with Harmony 0.9 and if I do the mouth setings with the cutter and color override my lip sync doesn’t work if i unchain it or clear it in network view it works well. But the bigger ishue is that when I export the scene all the characters has thin black line round the mouth, even I used the same color as on the rest of the skin. Why is that?

Thanks!
