Homepage Title Tag – Duplicated on all pages/posts

Hi all,

I have a few plugins installed but I can’t see to find this option. My Homepage Title tag is the title tag on all pages and posts. The posts have the correct titles but it also has my homepage title name attached to it. This kind of looks spammy to google…i’m wondering where and how I can disable this feature of mirroring the homepage title name on all pages and posts.

Thanks
