Valtan Normal Rewards

Guild and I cleared Valtan normal tonight. I even managed to be the one to finish him off. However at the end of it all, I claimed my rewards and requested to claim the bonus chest. After we all headed back to a stronghold to take some guild pics together, I noticed I didnt have the bonus chest rewards.

This is the history I have, I dont see the bonus reward chest information and I am certain I attempted to purchase it.
