Queries in Power query order changed, load enabled

I have the latest October (via the app store) release.  

I had 30+ queries neatly categorised in folders and ordered.  Most had loading Disabled.

I have unlocked my computer to find all the queries jumbled in order, most under 'other' and some folders gone.

All queries have had load enable ticked and refresh enabled.... it is a complex set of queries so i have had togo back to a prior version.

There is a little ? beside alot of the queries

is this a bug with the latest release?  it happened to a lesser extent a few days ago aswell.
