Hi carlton7372,
Welcome to the MSDN forum.
>> As you can see from my VS2017 screen the 'OutGoing Commits' is greyed out.
How did you commit the changes?
Please open
Changes page, choose Commit All to make your changes submit on your local machine, then, go to
Synchronization page, you will see the “Outgoing Commits” is highlighting.

In addition, this thread “Differences between
Commit, Commit and Push, Commit and Sync” might helpful for you, please take a look.
And, since our forum is discussing Visual Studio WPF/SL Designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System, and Visual
Studio Editor. And your issue is related to version control, if you want to know more about this issue, you could visit
Stack Overflow or
Developer Community, the support engineers will give professional advice.
Thanks for your understanding.
Regards,
Judyzh
