The only one that seems correct is the middle one that should be the group 6 if the picture order is the same.
For a double check you should use the app during the regen to verify if the duration value increases correctly and the soot value decreases down to 4-6 grams, more or less, at the end of the regen.
You can also skip the additional check and purchase the app immediately, considering that you can ask for the refund within 48 ours directly in the play store page:

If you have doubt reading the full app parameters, you can send me an email so I can check and confirm they are ok or not. Also for this test, the best moment for the check is during the regeneration phase.
