There is no option to select to train the jeweler to go from level 11 to level 12. See screenshot below.
I’m level 70 (95) playing on PS4. I received the plans for the Royal and Flawless Royal gems. Under Combine, under their respective options, it says the gems require “Jeweler Level 12.” But when you go to the training tab, there are absolutely no options. I have the materials and the expansion pack. I’ve even restarted the PS4 a couple of times. I’m stuck.
