P: When changing presets the profile resets back to Adobe standard, even if profile isn't checke

So what you are saying is you select one Preset that has a camera profile in it then you select a second Preset and it wipes out the first presets camera profile. Is that correct?
If it is that would be Preset Stacking, laying one preset on top of another preset. I'm not sure that was ever the way LR worked. But I could be wrong as I only use preset sparingly and usually only as a Base for other adjustment I make manually.

Thanks for bringing the issue to our notice Adam and Victoria. We are on it.

I'm also finding that my midi-controller is all over the place and pretty much useless now too, so having to do it all the  s l o w  way.

As for the profile part it is so all over the place that Im starting from scratch again. Just when I think I understand where the fault may be something else random happens!
and then it crashes, 3 times its crashed now!

(Oh, and I do agree there's a bug here...!)

What file format are you using Adam?  Oh, and what profile is it on BEFORE you select the preset?

Nope, the treatment and profile checkbox resets all the sliders so that is messed up too!

I can reproduce that between B&W and Color, but only on JPEGs so far, not raw.

I cant do a video but have an easy example.

Produce a preset to change the profile to black and white.
Produce a separate preset to change the clarity to +10 only (nothing else checked)

Select first preset to get black and white profile.
Select second preset for clarity and the profile changes back to Adobe colour.

In the second preset nothing else has been set so nothing else should change. However, if you select "treatment and profile" in the second preset then the profile is not effected. That is the opposite functionality to all other check boxes!
