Large DSD files not syncing

I have successfully synced my library in Audirvana Plus for Windows, but all files that are larger than 2 Gigs will not sync. These are all DSD files, usually of long symphonic movements. I would like to request a solution to this problem. Others have raised it, but no reply has been provided, so I am hoping this will elicit a reply, and, ideally, a resolution. It is my only issue with an otherwise excellent program!
