V767 BSOD (APC Index Mismatch) trying to Remove a Drive

V767 looks pretty good (I like the addition of the ReFS drives) but I'm having an issue when trying to remove a Drive.  I've tried a couple of time to remove a drive but both times got a BSOD with a APC Index Mismatch.  I'm now moving the files manually with the DriveServer service stopped between drives and the only thing I can see is I have some directories with Full Stops in them that Windows does not like, but I'm not sure if this is the issue.  Windows did create Mini Dumps (Attached).

Thanks
