title same on all pages

i build this wp site with a theme that is purchased

i also used seo plugin from yoast and although i never had problems with this for this theme it doesn’t work

for some reason every page has same title and no meta description. I entered all info in the fields necessary but nothing… also forced re-write doesn’t help

check out this page for example that is fully completed

i hope someone here knows what to do

i tred othe ttle tags in header, but nothing
