Mixing Canon Speedlite and Profoto system

[ Edited ]

Hi All,

I have recently found out a way to use Canon Speedlite and Profoto system together using this method.(Outsside link removed per Canon Forums policy) 

Camera Settings (see the attached photo)
Canon 5DM3
Canon 580 EX II
Pocket Wizard Mini TT1 on the camera and Flex TT5 on the 580 EX II
Profoto A1 / Profoto Air TTL


This method works for a few shots by firing bith Canon 580 EX II and Profoto A1 but Camera suddenly changes the setting to this flash compensation mode, not listed in any canon reference or manual (Sorry, I don't know how to attach the photo of my camera LCD but it looks like speedlite +3) and does not fire Profoto A1 and ultimately shutter button gets stuck.
Do you know what this called? Can I do something to prevent this from happening? At this point, the only way to revert is to turn off the camera and Profoto Air TTL and start all over again.

Thanks in advance,
