Art boards disappearing upon opening

Hi- I'm running into an issue where if I have multiple artboards in a file, save my file as an SVG, and close it, upon reopening the file all but one of the artboards disappear. The artwork is still there, and placed as if the artboards were still there, but the actual artboards have disappeared. 

note that if I am not choosing "save to artboard" on the save screen. This only applies to those files that I save with multiple artboards. When I chose "save to artboard" each artboard separates into a separate file and there is no issue there. This only occurs when I have multiple artboards in an svg file.
