It's why we should keep Systematic Theology in Mind. Jesus was Resurrected in a Spiritual Body; one that he called Flesh and Bone, All the while differentiating himself from a Spirit. There are good reasons to have Theology...
Where did Jesus say he was resurrected with flesh and bone? And what was the reason he said it?
It looks like your line of reasoning is pitting a saying of Jesus who was not teaching about the composition of the resurrection body against what Paul said when he was teaching about the resurrection body.
1 Co 15:35 But some one will say, How are the dead raised? and with what manner of body do they come?
He answers:
The resurrection body is not made of dust (1,3), it is of a heavenly nature. (2)
