"Print Settings" are not stored in the print preset

Question

Hi everybody,
It seems that, no matter how many times i save and update the profile, all the print setting (image size, sharpening, bit depth, color management, ...) are store within the preset, all but the Epson Driver settings, which have to be selected every single time.
I really can't remember if this bug was present in 4.0 or not (I'm currently running 4.1 RC), but I'm quite sure it was working OK under 3.x. Here's the thing.
I configure the printing settings and create. a profile: Profile1.
I change all the settings and create a second profile: Profile2. The "Print Settings" settings are different, same printer, one for Color (Profile1), one for Advanced B&W (Profile2).
I click on Profile1 (which was created with color Print Settings). Clicking on "Print Settings" or "Print", the printer settings selected under the epson driver is the ABW one (the one that belongs to Profile2).
I reselect the correct setting from "Print Settings..." (Color).
Click "Save" again.
Righ-t click on Profile1 -> Update with current Settings. Setting seems to be saved.
I then click on Profile2 and bam! The "Print Settings..." seems to be rverted to color instead of ABW.
Update the correct settings, back to point #3
Can you reproduce this? This behavior is vanishig the power of the "Print One" button, unless you constantly print with tha same Driver settings.

I may have resolved the issue.
The bug is there, because the name of the preset is kept as the last used, which is wrong.
If you revert to the default "Default Settings" Epson preset, and change all the parameters as you like, then click Save and update the Lightroom preset, the settings are stored correctly.
You'll have to check every preset (I have two dozens) and re-update with the new correct (or wrong?) Driver configurations, so that you could have faith again in the "Print One" button.
