October 2018 Update - Recent Sources Issue with SAP BW

I've discovered what appears to be a bug in the Implementation Selector for SAP Business Warehouse Application Server using the 1.0 Connector. When I attempt to add a New Query using Recent Source I receive an error message and selecting Edit just loops back to the same error message.  The error message reads:

Unable to connect

We encountered and error while trying to connect.

Details: "Token Literal expected."

When I set up a new source I see the selector for Implementation 1.0 or 2.0 but even after removing recent sources and setting up a new source with the 1.0 Implementation selected the Recent Sources option does not work.

Is this a known issue?  Is there a suggested work around or fix aside from always using New Source when connecting to SAP BW using the 1.0 Implementation?
