Forum:My defense deck is'nt registering correctly????

So here's the story. My Defense Deck 1 is currently (COST) 119/178. It's defense is 123 152. When I go into battle, I noticed that my defense is 116 487 or something like that. I went into "Edit Deck" and raised the priority of Defense Deck 1 or Recommended. The defense is still the same even though I raised the priority and I have extra cost left. My question is, ' why is my defense low when my cost and priority is raised? '

BTW, my Attack Deck registeres my attack correctly.
