Byzantines grand winery has no option to train monk in castle

I have been playing with the byzantines and for some reason i cant train monks in castle age. Im on xbox and play with mouse and key, i tried to reset my controls to default and switched between fully remapable to grid with no avail. Once i am in imperial and research the imperial age food gathering tech the monk will appear in that spot and be able to train but in castle when i research the tier 2 food tech the imperial one appears grayed out. I havent seen anyone else mention this so im hoping its an easy fix. Thanks.
