Superstar import pixel tree kit

[Steve28]

I'm running into trouble when I try to import a pixel tree into my preview.  I open the preview, click add, go to super star props and choose a 16x25 pixel tree kit.  This creates some channel errors which I am able to resolve.

When I save and return to the sequencer the row that contains the pixel tree has a gray pattern on it and I am unable to insert my superstar effect.  Any ideas about what I'm missing here?
