Can anyone help me understand why there is such a big discrepancy between the eligible spend listed on my PDF receipt that can be downloaded from Hyatt.com and the eligible spend listed on the mobile app?

Both of these taken this morning at the same time (now). Neither one makes any sense apart since at the very least I think my eligible spend should be $600 (at $300/night before taxes and fees) if not higher. The all in total was $915.47 before a $200 room credit. What am I missing before I go to Hyatt and try and claim what I think are missing points?
