Excel Extension blank window - no full ribbon on Create or Open template

I open Extension v10.01.1683 from Cloud launcher. Open project and select to "Create" a new report. I then get a blank excel window with no sheet visible. The ribbon does not update to the full ribbon to allow me to add tables etc. 

This is not just unique to my machine. I am seeing it on colleague's machines too. 

It doesnt seem to make any diffence if excel is already running or when launching the Excel Extension. 

Is there a straightforward solution/change of setting to resolve this or does it require more investigation?

Thanks
