Moon seemingly orbiting nothing

I have no clue why this happened, but I was making a dwarf planet extension for the base Juno System, I tried to make another moon for a certain object, and... Yeah. I don't know if this is a visual glitch or something, but I'm sure that isn't supposed to happen.

Update: It was just a bug with the time warp in the planetary system editor, all I had to do was unpause the time. I still think you should fix it though
