File Renaming SW2015 via Windows Not Completely Working

I am finding that renaming files via the right mouse click option in Windows Explorer for SW2015 does not work as it should - as it is not locating 'where used'.

This is via windows explorer

No Where Used listings

As such, when I go to open the assembly after having done the renaming I have to tell SW where to find the renames parts.

If I do this via SW Explorer, the Where Used is located and there is no further issues when opening the assembly where the part is used.

Is t here some setting that needs to change to use the SW Renaming function via Windows Explorer or is this a Bug?
