Ok folks, figured it out....The weirdness came when I copied a scene (save as) and didn't notice the the visual of the fixtures in the lower right hand corner, reassigned the fixtures to another position. Could I have done that inadvertently, sure, but I'm 99% positive that the fixtures were moved. I have 14 fixtures set up for my stage and the locations are static. I did learn a lesson to assign a name to each fixture as a fail safe.
