I’m able to manually delete or edit the data. But I think we need a discussion about what we should do with the map. As there are a lot of people, who has build LR3 and after answering to the query they have upgraded LR3 to LR4.
We have option to leave all machines to the map and then the map shows all build’s ever made. Or we can update all data so the map would show all machines that are existing now.
Unfortynetly I don’t have time for any big update process atm.
