While submix level is down i still hear the original tracks

i thought that if you send a few audio tracks to submix and put the level of the submix all the way down you shouldn't be able to hear those audio tracks anymore at all, but for some reason i still do. it's firmware version 3.6 by the way on MPC One. Does anyone know what might be going wrong here?

never mind, i figured it out. i still had send effects on the original track. That was where this sound came from
