[MlMt] Cannot remove source

[Jon Sutton]

I finished a consulting gig with an organization and no longer need the source connected to that organization’s Gmail account.  I removed this from my laptop by right clicking on the source and selecting “Remove Source”.  When I try this on my desktop Mac, “Remove Source” is grayed out on that menu.  That source is offline since I do not have valid credentials for it.  Any ideas how I can get rid of that source?  Thanks.
