Hey, guys! Having a little trouble with my portfolio option in the otherwise great soledad theme.

So the trouble seems to be this:

I set up my portfolio as a masonry styled 3 columns page and it works perfectly fine while I'm previewing it. But as I publish it and click on the menu, it appears as a photography posts page, with the head title "Archives", without the filter. I've tried to customize it in "General" options, but the look is not the same. Help me, please?

Screenshots attached. If you enter the website, the portfolio will be the second link in the menu. I figure it has to to with some general options, but I can't find where and what to fix
