Greetings, For some reason, I am not able to select the different flash intensities on my EPL2 as they are greyed out including the full, 1/2, and 1/4 settings. The "Fill in", "slow", and "slow 2" are selectable. I am using the same lens and was able to select all flash light intensity settings before, but I am not able to do so now. Is there perhaps a setting that needs to be adjusted? Appreciate any feedback!
