File path issue when exporting multiple DWFs

My title block uses the default File Path label parameter.

When exporting a single sheet DWF, Revit generates the correct file path on the DWF:

C:\Users\usr\Documents\RevitFile_usr.rvt

However, when exporting multiple sheets to DWF, Revit generates this file path on each DWF:

C:\<host>

I started noticing this issue once I updated to Revit V16 R2 (with the RevitWorker feature). I'd like to be able to export multiple DWFs with the correct file path. Please let me know if there is a fix for this.
