Catch Box Theme: Title Problem with All In One SEO

Hi,

I have All In One SEO installed and have been using it for years. I recently changed to catch box theme. On the posts that I have entered info in the plugin, the post title comes up fine. In those that I haven’t, it comes up as

Blog Title Post Title.

I recently changed the theme, I love the layout and look, but my visitors have already dropped substantially and I am sure that this isn’t great for SEO, my page titles in google are messed up.

When I disable the plugin it turns into Blog Title >> Post Title. I have around 300 posts and I really don’t want to be losing the benefit I already have. Is there some solution so that i can keep All in one SEO and the theme running together? I have been looking through the php files but honestly am struggling in that area.

Here is an example of a post without the All in one info plugged in.

It is also happening in tags.

Appreciate the help!!
