FSX black props

I have been loading some new FSX aircraft... Lancair, Spartan, and
Howard. The spinning props, are black, and show strange reflections of
clouds and see through distorted scenery instead of the normal transparent spinning blades. I have loaded these aircraft in FS9, and the spinning props work just fine. Any clues what is happening here? These
aircraft fly and sound super on FS9 and FSX ...I truly want to fly them on FSX with props that make sense.
Thanks for any input
