ProjectWise Managed Workspace for OpenRoads forces Copy Out of files in active folder

I have configured a Managed Workspace for OpenRoads Designer in ProjectWise, using the UK standard dataset, however when opening a file using the assigned Workspace it is forcing the Copy Out of all files in the same folder.

  • There are no references attached to the file being opened
  • MS_RFDIR variable has been "Undefined" in all CSBs
  • MS_RFDIR has been added to "Variables to be excluded from copy out" 
  • Link Set seed.dgn has been removed, but files still copy out

I can't see any other variables in ORD that define the active directory, so out of ideas of what to further exclude. 

Question is - how do we stop the force copy-out of these unrelated files?
