If the value in Acct 2353 is in [Parent Total] but not in [Proportion] then the value is either not being consolidated or is being set to zero when calculate executes on [Proportion]. You could put some audit text in the final field of the HS.Con for this Acct 2353 and then check to see if that creates an automated consolidation journal. If the journal is there the problem is in Calculate. If the journal is not there the problem is in Consolidate.
The application must be corrupted. This was a test app, and when I load the same data and metadata in another app, it works fine.
