This is a known old problem never fixed. 

gnubg stores the double decision and take decision as a separate moves,
so you can individually evaluate both. I'm not sure what the best
solution is: (a) ensure that updates to one evaluation is propagated to
the other, or (b) only store the evaluation for the double decision, and
change the GUI/export so it uses the numbers for the double decision for
the take decision. Or a third solution?

Since nobody is working on this, I suggest you create a bug report at
