18.2 Beta. How to disable! EYESORE and DISTRACTING NOISE!

MY iphone just updated to Beta 18. Now there are what appears to be category pictures next to each email as displayed on the phone. It is an eyesore and distracting to see or follow emails cleanly with this feature. Ok to have those pictures if people categorize or choose categorize option, BUT I DO NOT. Does anyone know how to disable this odd and useless picture? I have tried LIST VIEW option, but it did nothing. Thank you!
