But the date and the person are exactly the same and the place is close.
In simple terms, close does not count in horseshoes, hand grenades, nor Rootsmagic ! It never does anything via assumption (ie. being close) That's why you are having to go through this reconciliation process to effectively merge two different individuals (in Rootsmagic's determination).
They are considered two different people (by RM) if any white (or yellow) exists anywhere. Now, pause and re-read that.
I still don't know why the marriage does not appear aligned and is 100% white.
That's what I have been expecting this marriage to look like.
No, you've been expecting them to align because they're a matching fact type (and even a matching Spouse) ...BUT with "close" event Place names. Now go back and look at the Place names for that Marriage fact. What color are they? Not green, right, they're white? And what does white equal? Referring again to the RM approach to determination - they are still two different individuals with same name (and even spouse) BUT different marriage Places. This applies to all the other fact types also ...see Birth, Death, Burial for existing white(ness). The vertical ordering of fact types underneath (and within) each section (Vital, Other, and Family) is merely a pre-formatted order, not for purposes of alignment (per se).
