Can't turn Use a Data gateway off

Hey everyone,

Hoping someone here can help.  

I originally started my Dashboard with an Excel file while I awaited direct access to SQL.  As a result, I set up a gateway and everything was fine.

Fast forward to now and I have sql access, and moved all my visiualization soruces to ther sql databases.  Since I no longer need the gateway, I deleted it.  However, I can't turn it off because the option is grayed out.

For extra background, I had deleted the data from the Fields list (and it warned it was in use).  I then had to go query Editor and delete synch logs referring to the Excel files and was THEN able to delete the excel sources and they stopped appearing in my Options->Data Source box.

The bahavior SEEMS to be that Power BI thinks I am referencing these local files SOMEWHERE, so it is enforcing a gateway but I don't see where.  In the meantime, I'm gettign local accounts to add SQL to the Gateway for refresh, but I'd rather not have to use a gateway at all.

Any ideas?  Any ways to see what is being referred to (perhaps from these local files) and where?

Thanks!!!
