Select silent on file manager

[AC Question]

Hey guys,
I'm using a galaxy s7 edge but I still get sound notifications when my phone is set to vibrate. I went to the Gmail settings page, clicked on my account, clicked on the inbox sound and vibrate. However, when I click the notification sound tab (to set it to silent) theres no option, all that pops up is a file manager screen where I can set sounds from the device or SD card, no way to select silent.
Thanks for your time,
Matt

Welcome to Android Central On my Nexus 6P, it shows as "None" in the list of all of the tones (although once selected, it shows up as "Silent" in the Settings menu). "None" is at the very top of my tones list. You don't see it there?
