Importing vector images into Flash

i’ve got a few vector images of fruits and breads that i exported as SWF in Illustrator.

when i imported the bread vector file into Flash, for example, the gradient portions of it becomes a fuzzy bitmap while the solid-fill areas are retained as vectors.

don’t understand why this is happening

i’ve had no prob importing gradient vectors into Flash before, but somehow this lot of gradient vectors are turning into bitmaps instead.

hope someone can help me out!
