It could be that the double blooming one has used more nutrients than it has available to it. Feeding with a light nutrient solution can help in this case.
Alternatively, I would check the leaves, carefully, for any signs of insect infestation or fungal infection. Both can cause a freak flowering, and the decline of the tree.
Here is an article for more information on the care of these trees:
