Health bar is obscured by nuclear missile gauge

If you see the image I included, the health bar of a rock worm just right on the middle of the map is obscured by the nuclear missile gauge. This is very annoying situation. At that time, the nuke missile was just close to launch and I had to choose to attack one of them. And I was not sure to attack the rock worm on the middle, because I couldn't figure out his remained health was low or high!
