Can't remove default site name from meta title of every page

Hi.

I got some trouble with my meta on my site. My site’s name is InvestEd and every single page on my site’s meta starts with InvestEd. I installed the Yoast plugin and created some default metas but they won’t work. I have set the Yoast meta to include my sites name after not before eg. the post name on my posts.

This is my site: InvestEd

Thanks in advance
