Site title SEO question

Hello all,

I'm quite new at things and I've ran into an issue for setting up seo title on a website I just did. For some reason after setting up SEO I noticed when searching the website that it appears as  the following – Your site title - (Shows my title here). I'm not certain what I'm doing wrong I have changed the SEO settings inside the SEO Appearance section under site title and followed the following format of %s - ICI Systems, Inc. I have individual seo settings for each of the pages as well what seem to work fine. I just can't get google to drop the "Your Site Title" portion. I'm investigating further but would really appreciate if someone who knows this issue could maybe point me into the right direction.

Thanks in advance

Mona
