Can't Access On Camera Flash Control Menu on Canon 6D with Yongnuo 622c and 568EX II

I have a Yongnuo 568EX II ETTL Flash and a Canon 6D and I recently purchased a couple 622C triggers so I could use them for ETTL and most importantly changing the manual power setting through the on camera flash control menu. The prolem is I can't seem to get the Flash control menu to appear. I've gone into the menu screen and it's not avaialable. Everyone said that the 6D worked with on camera con trols for this. Is it my Flash that's the problem. It shoots in ETTL fine but I want to be able to externally control my manual settings otherwise the 622c is a waste. Does anyone have this setup and can offer some help or guidance. The triggers are in Remote mode not mixed mode. Thanks.

The first thing to check is that the on-camera 622 is fully seated in the hot shoe.

I did that. The ETTL function works fine I just don't have remote control to change settings. My camera isn't offering it in the menu. I've taken the triggers off and put them on several times with no change. Made sure both triggers are set to remote mode not mixed mode as well.

I finally figured it out. I eventually found the menu setting. I was looking for the wrong name of the function in the wrong area of the menu. All the reviews and info I found online showed the menu item as being "Flash controls" which was listed in the first menu section along with the Image Size. But it was actually in another menu and it was labeled "External Speedlight functions". I don't know how I missed it before or maybe I did something different when I kept taking the triggers on and off and reseting modes on them but I eventually figured it out. Thanks for the help.
