Thanks Gary, The needed temp 12 hours ago explains why 144 records could not be calculated because I started with an empty database. I have to backup two databases with the same missed data, so I will use the export of this database to import it in the two databases of my two vantage stations.
I have the wu import set to 14 batches of one month each. Half way finished so far.
