Hi,
I have the this Problem with Probe Matching:

• Create a profile without probe matching and save it. (bcs file contains the line<probe_matching_enable>false</probe_matching_enable>)
• Open the profile, configure matching and set check box "Probe Matching active" in the Graph options
• Set a new name and save the profile. The Manage Spaces Dialog shows, "Matched", what is obviously correct. (bcs file contains the line<probe_matching_enable>true</probe_matching_enable>, and also probe_calibration_ref and probe_calibration_active
• Open the matched profile again. The matching data have gone and the checkbox "Probe matching active" is not set any more
• Set a new name and save the profile again. The Manage Spaces dialog does not show "Matched" any more. bcs file contains the line<probe_matching_enable>false</probe_matching_enable>
• Open this profile again. The measured data are corrected with Probe matching, but no information about probe matching is available.

As per the User Guides, the probe match data has been burnt in to the second profile you saved.
You should NOT re-apply the probe matching to the second profile saved.
By saving the profile for a third time, you are overriding the metadata for the matching!
(You definitely SHOULD NOT save for a third time!)

In my opinion, there is still room for improvement. When you save a profile and then reopen it, you get something different. This is very surprising and leads to errors. When opening a profile that was saved with "probe matching active," the behavior should be the same as it was before saving.

You actually get exactly what you saved when you re-open any file.
If you save a file with Probe Matching Active, the probe Match gets 'burnt into' the file, so when you re-open it the match is burnt-in.
In the library metadata it will show the file as 'Matched'.
And you MUST save the file with Probe Matching burnt in if you want to use the Probe Matching when making a LUT.

Very simple really, and is all explained in the User Guides.
And is very unique, as no other calibration system can apply Probe Matching AFTER profiling.

Sorry, I still find that this is strange.
Save a profile without probe matching and open it again, and you can continue with your work just as you had never saved and reopened the profile. For example you may re-measure certain patches, that you recognized as outliers.
Save a profile with probe matching and open it again, and you can't continue with your work. And you even cannot see which probe matching was applied.

So I will accept the current situation and change my request to the category WIBNI

You have described the workflow correctly!

If you 'save' a profile with Probe Match burnt in, you have fundamentally made the data fixed.
The original profile saved WITHOUT probe match active can be modified as the data is still original.
It is like taking a RAW image and making it a JPEG.
You have restricted what you can then do with the JPG image vs the original RAW image.

There is no WIBNI.
