6d External Speedlight Issue

Maybe someone has an idea what is going on.

I have a ST-E3-RT and 3 600ex-rt's that are working on my 5dII.

When I use them on my 6d (external flash enabled, flash firing enabled) the flash isn't firing.  The weird thing is that the image meta data says the flash is firing.  I tested this in multiple situations, the flash isn't firing.

I checked and I have full channel signal strength.

I'm guessing the meta data means it sent a fire signal to the radio transmitter.  Pressing the test flash button the master flash unit always works.

It doesn't seem to matter which unit I set as the master  (i used different 600's as masters and I'm having the same issue as with the ST-E3-RT.

I'm guessing something with my 6d settings is messing up what I want to do.  Any ideas?

Any help is much appreciated.
