Didn't receive full rewards from Conquest

           Last Conquest which ended yesterday, I was playing to win with the new JTL 'Jedi Training Leah.' Normally I only go to the gold crate on Normal Conquest, but since it was a character that I liked a lot, I went and got red crate. 

I added the total shards of all the crates together, and it came out to be 75 shards which I would receive at the end of the event. However when the end came, I only got 25 shards of JTL, and i dont understand why.

Ech crate is supposed to be guaranteed rewards, so why didn't I get the full rewards for Conquest?

"Also this has happened for the last two Conquests as well. If im wrong and anyone understands whats happening PLEASE tell me because im very confused."
