@coolo upps, just ignore it, I manually changed the class on the html element in the browser to get all the states into one screenshot ;)

I think this should be some shade of yellow. Both are intermediate steps between building and the final result (green/red). You can not really do much about this state, it shouldn't be as heavy as disabled/blocked.
