I see new buds forming on the branches, perhaps you are just having an anxious moment?
I think if you just exercise patience you will be rewarded, and the tree will have low branches by the end of the year.
Things to consider with young trees; what is their natural shape out in the wild? are they a tall tree or a short tree? How many branches do they normally have close to the ground when growing in the wild?
All plants want to follow their normal growth patterns, when we take cuttings to grow new trees, we have started from a point the tree isn't used to dealing with so we have to train by bud pinching to encourage a growth pattern like a tree from seed would grow.
