Adobe Portfolio Matthius Theme Navigation Text Style Issue

I Love the Adobe Portfolio sites & the Lightroom Integration!

However, In the theme I've chosen Matthius (due to lightbox text behaviour in DT & Mobile pages), the Navigator colors make No Sense!

Let me explain. In two sample sites on your Examples (https://portfolio.adobe.com/examples/), several of the sites navigation text colors, are logical.
The title of the active page is different. This of course gives visual confirmation of where the user is in the site.

HOWEVER, on other sample sites the logic does not follow.

On both my test sites, the colors also are not following visual confirmation logic.
(Please excuse the mess. I haven't created any custom collections in lightroom yet to import so the imagery is just from just what was available. Plus every time I reset the theme I lose stuff I was working on.)

Going to the home page of
https://cxg1398879.myportfolio.com/
Instead of the "WHAT" hompage being (highlighted or different),
The "WHERE" page is! ???????

When I am on the "WHERE" page, "WHAT" is highlighted.

When I am on the CONTACT page both "WHERE" & "WHAT" are highlighted.

"WHERE" & "WHAT" are collections but that appears to be as on your site and yours works!

I've gone back to reset the theme a number of times and created the 2nd Matthius theme from scratch but the issue persists.

My 1st Matthius theme
https://cxg139.myportfolio.com/
is in the dark mode has Collection & other pages & the text colors make even less sense. ??

I've viewed the pages in MS Edge as well as Chrome.
I've scoured the web for help and the Adobe Portfolio Help seems to be a confused shambles right now as well.
