CredentialHelperSelector Prompt Totally Confusing

Every time I update to the latest release of SourceTree, I am confronted with the CredentialHelperSelector prompt. I see with the latest release there is actually a new "Always use this from now on", and maybe this will resolve my issue, but how am I supposed to know which if the items listed in this prompt is the correct one to choose? Each item (with the exception of "<no helper>" is listed twice. Where is this info coming from? Why is each one listed twice? How can I clean it up? I'll try to attach my screen capture, but not sure I will be allowed to do so.
