C300: Reality Check needed!

[Mark Smith]

A friend called me today with a C300 mk2 question that I couldn’t answer. We discussed over the phone and I had my camera in hand and looks like I confirmed his suspicions.
It looks like if one has a custom camera profile selected in the menu ( one that was user created or dowloaded whichever) and then you step back in the menu and activate one of the factory presets, lets say C Log 3 - 709, that the 2 camera profiles can stack one on the other with some funky effects. I had been turning the factory presets to off, then activating my custom preset which was ok. He was using my custom profile and had a factory preset selected and it seemed like the color profiles were stacked one on top of the other.
Only by toggling the custom preset to a vacant position and then selecting a factory preset, were we getting exactly what we expected as results picture wise.
So to sum up. Either have a factory preset selected with custom profile set to some empty memory slot, OR custom preset selected with factory presets set to off.

I had been following the latter scenario and getting predictable results and he had been been shooting with both a custom preset enabled and a factory preset enabled and getting terrible results .

Any thoughts on this and has anyone else noticed this issue?

Tried to replicate- didn't happen (using latest firmware: what firmware exhibits this behavior?). If I select a preset, it visually takes over. If I select a custom picture setting, it takes over, and turns the preset to off. Not sure what you mean by "empty slot" for CPs. They're all used, set up with factory defaults. I've modified and am using all 20. Perhaps report exact repro case & firmware to Canon?
