Scorched Satchel of Helpful Goods and Tranquil Satchel of Helpful Goods not showing anything in tooltip for rewards contained within. all the previous tier dungeon rewards at least showed something (manually checking, i am missing all of the reward tmogs from those bags)

This is because in 7.3.5 Blizzard changed all the bag itemID's. The Cataclysm/Panderia Bags are probably using the old ID number. We'll get that changed to where they use the new numbers and will once again work the way you described.
