[AAU2] - W and B constant 5's in the values - sometimes

The W and B UI is too flakey. On flight start up you get a constant set of 5’s
in fake station positions. The empty CG MAC % position is set to 5% when it
should be a different number (48% in my case). I don’t know if my aircraft is
setup correctly if/when I see these incorrect values. Doing a change to the
station weight (ie. changing 170 to 169) seems to make the empty CG %MAC go to
the expected value. I assume C of G is ok as the checkered circle does not
move a lot. Closing and reopening the W and B UI sometimes makes correct
station weight appear, however the empty weight CG MAC% remains at 5%
