Need Help Restoring Separator For Site Title & Tagline/Page Name

I’ve been screwing around with this for a couple hours now and I’m at my breaking point, so time to ask for help. Something is messed up with the separator for my site title and tagline/page name. I remember at one point I wanted my front page to just have the site title, no tagline. However when I removed the tagline there was still a hyphen or dash.

So here’s the issue, I did something to make that happen, not realizing it messed with all my other pages. I didn’t realize it, but by clicking around I saw my titles are all messed up on my tabs. Take a look at my main site and then click on any other page, noting the title at the top. Please I’m pretty fried, I just want to get my site back the way it used to be, I’d appreciate any help. Thanks!
