Mirroring Glitch

With Symmetry in the new Beta version, When you detatch an object that has symmetry from a fuel tank, let go, and then go to put it back, it shows where the symmetrical objects would be placed, but upon placing the object, they do not appear. When you try to put symmetry back on the object, It says you must connect it to a fuel tank, but it is already connected. The Solar Array in my screenshot has mirror symmetry enabled, but nothing is mirrored.
