Toad v12.5, source control add file option reopens file in second editor tab

I just installed Toad for Oracle v12.5. I am not using team coding, it is just me. When added a new file to source control (Visual Sourcesafe), the file is added to Visual Sourcesafe correctly, however the file is reopened in a second editor tab resulting in 2 tabs showing the same file. Is this a bug or an option that I cannot find that enables this behavior?

Thanks, Gregory Miller
