Build Forge 8.0.0.1 - Windows 7 - RTC 4.0.5 - JazzJBE - error trying to set directory to BF work area - why?

I am running Build Forge 8.0.0.1 on windows 7. I have the BF console and windows bfagent running on windows 7. I have a 4.0.5 RTC server on a separate host. I created a BF job to  just execute a "Fetch and Accept" using the ".source JazzJBE" command. I have an RTC build that kicks off the BF job and comes back with "completed successfully" status. However no source files are extract into  the build workspace on the windows 7 host. I keep seeing the following error.

Unable to set working directory to 'C:\BF_SERVER_BUILDWRK\Test_Ant2\BUILD_1\Test_Ant2\BUILD_1' (2).

When I look - there is this directory -- C:\BF_SERVER_BUILDWRK\Test_Ant2\BUILD_1   --- but not a "duplicate one underneath.  Any ideas why it is trying to do a "set working directory" to -- C:\BF_SERVER_BUILDWRK\Test_Ant2\BUILD_1\Test_Ant2\BUILD_1 --   instead of to -- C:\BF_SERVER_BUILDWRK\Test_Ant2\BUILD_1
