Pomerania "Control the Lower Elbe" mission bug?

[Reignspike]

Unless I misunderstand, there appears to be a bug in the mission completion parameters for Pomerania's Control the Lower Elbe mission.

I formed Pomerania from Stettin. I completed the prerequisite missions, and believe I have completed the parts of the Control Lower Elbe mission, but it won't update.

My understanding of the requirements matches what's in the wiki. To wit:
"4 provinces in the following areas are owned by the country or its non-tributary subjects:

• Lower Saxony
• Schleswig-Holstein"

I own Schleswig, Holstein, Lauenburg, Luneburg, and Celle (5 provinces in Schleswig-Holstein & Lower Saxony areas), but as you can see on the screenshot below, it says I currently have 0 of 4 needed.

It's possible my understanding is incorrect. Sometimes the requirements are a little difficult to understand, given how they're organized more for coding purposes. If that's the case, could someone tell me what it really means?

This should be better posted in the bug reports forum.
The trigger of the mission is:

        trigger = {
            num_of_provinces_owned_or_owned_by_non_sovereign_subjects_with = {
                value = 4
                OR = {
                    lower_saxony_area = {
                        type = all
                        country_or_non_sovereign_subject_holds = ROOT
                    }
                    holstein_area = {
                        type = all
                        country_or_non_sovereign_subject_holds = ROOT
                    }
                }
            }
        }

I have never seen such a combination of num_of_provinces_owned_or_owned_by_non_sovereign_subjects_with with area-scopes+type=all. I think it doesn't make much sense. I tested the mission and it gets fulfilled if you completely own one of the areas(it shows a bogus number and you can even fulfill the mission by just owning the 3 provinces in the Holstein area), but you can't fulfill it by owning 4 provinces over two of the areas.

I think the trigger should be the following instead:

trigger = {
            num_of_provinces_owned_or_owned_by_non_sovereign_subjects_with = {
                value = 4
                OR = {
                     area = lower_saxony_area
                     area = holstein_area
                }
            }
        }
