I eat strictly low carb, but like you, need something a bit sweet occasionally. That's when I have a bowl of diced canteloupe - high in potassium - with greek yoghurt. If a couple of dates is working for you, good. Your PCP won't know how other people may react to a particular food or medicine. Many people just follow the current "superfood" ideas without knowing what oxalates are, or how they combine with calcium to form calcium oxalates.
