I tried it but am missing the file "C:\Common\Error Handling\Insert_PossibleReason_In_Error.vi", so I deleted that and ran the build spec and got the same thing you did- it's showing up as an ExpressVI.
It's interesting to note that, despite your setting for Dependencies to be "Include if referenced", the vim doesn't actually get created in the source distribution. If you manually set it to be "Always Included", it'll put it in the distribution but it still doesn't seem to link it correctly.
