I do not really know about the triangle but the problem with the hair is that it is now located somewhere away from the head. Perhaps you can see it if you zoom out enough. This happened sometimes with ready made poses with me also. What I do is locate the hair from the menu under the image window and delete it. I then add the hair again and it comes in the right place. I am not that advanced in poser to offer a better explanation or solution but that seems to work OK.
