FZ150 RAW in IA mode??

This past weekend I learned how to use Lightroom which is the first time I ever did any post processing.

Since I will probably at least look at all my future images in Lightroom I decided I might as well start using RAW. I set it to RAW and jpg. I took three pictures in P mode and three in IA mode. I had an unpleasant surprise when I exported them to my computer.

Why won't it create RAW in IA mode??
