ATEM Software Control - paste camera settings greyed out?

I have 5 BMPCC 4K connected through HDMI to a mini extreme ISO. I can remote control my camera from the Cameras tab of the ATEM Software Control and I can copy the camera settings from the 3 lines burger menu on the Color correction of one camera.

Nevertheless, I cannot paste the copied color correction to another camera nor to all cameras, since those 2 menu options remain greyed out.

What am I missing or doing wrong ? Any suggestions?

Thanks in advance!

be shure all P4 has the same firmware and no repeater or splitter between HDMi

I have the same problem. Is there a solution?
I have 3 BMP6K and ATEM Mini Pro & ATEM Mini Extreme. All cameras have the same software (6.9.6)

Thanks
