Glad you have it. Sorry for delay in response.
Do you have multiple camera bodies? There's some quirks to how profiles are used, and two (sort of mutually exclusive) approaches that may help if so.
The profile file itself has a name. In windows for example, I have files like this:
C:\Users\Ferguson\AppData\Roaming\Adobe\CameraRaw\CameraProfiles\Alico LED D5.dcp
C:\Users\Ferguson\AppData\Roaming\Adobe\CameraRaw\CameraProfiles\Alico LED D4.dcp
Obviously the path will be different in Mac but my point is the last part, the file name. By default this is the name you give it when you do the export. However, that export also puts a name internally and it is the internal, not the external name you see in Lightroom.
What I do is name the export WITHOUT the camera name when producing it. So for each of these my name was "Alico LED" (Alico is a stadium, and it got new LED lights). After I export it for my D4, I rename the file manually to include the D4 name, and do it again, rename with D5 name. That gives me two profiles with the same internal name "Alico LED" but (as required of course just to exist) different external names.
When Lightroom is restarted it finds these, and this allows you to use the same profile name across different camera bodies, and Lightroom sorts it out which to use. It will not mis-match a profile and camera type (it uses internal identification); in fact it will not even show you a profile in the drop down for the wrong camera.
The other approach is leave them named differently, then you either manually do it by camera type when assigning the profile, or include it in the camera default setup.
The reason I prefer my way is I have lots of different profiles by venue. So whenever I do a shoot, I come back and manually attach the venue's profile. By doing this, I can attach it to one shot, and copy it to all the rest, and it sorts which camera's profile to use and I do not have to.
On a distantly related note, unlike develop presets, profiles are not "baked into" the develop settings. Changing them will retroactively change any photos developed with them (not instantly, but when re-evaluated for export). Also, if you move lightroom to a new computer, you must preserve them. Effectively you should, if doing new versions, give them new names and always keep all old versions forever (unless you want to allow new ones to change old photos). They don't explain that very well in most documentation.
