Hello Boho Blog

I was having some trouble and made the mistake of not creating a backup and switched to a different theme briefly to check something. After switching back I realized I am now missing some times, such as New On The Blog on the homepage. In that spot it just says Homepage. I checked and rechecked settings, but haven’t been able to change it. When I go to my Blog page, it no longer shows the slider/optin. And the Featured Images are larger than they were. DO I need to redo the demo in order to get it all back? I don’t want to lose everything that I’ve already added. Also, the About image on the home page is now small for some reason and I can’t sort out how to fix it.
