Cake Mode and Villager Trading

Device: Samsung galaxy s6 edge

Problem: When Cake Mode Addon Behaviour Resource is being used Villager trading is not working.. Instead of the usual "Trade" button there is an "Open" when facing a villager to trade..

Test: Villager Trading was working when i removed the "Cake Mode Addon Behaviour Resourxe pack".. but when i turned it back on Villager trading is not working again..

Screen shot the "Open" button instead of the "trade" button included..
