Fillet causing floor plane to offset

I'm having a very weird problem where one of my fillets is causing the floor plane to offset resulting in the part appearing to hover. I know it's "Fillet2" as I rolled back to find out what was causing it. It won't even allow me to manually define an offset to the floor via scene settings. When I do the part remains suspended in air.

Thanks for any help or ideas.
