avoid displaying the same map labels twice

Problem

Disable map labels when it is exactly the same as the one in the .trees files? (not of the whole map, just the ones that are displayed twice)

Quite involved to do:

• we do not store map labels for the uploaded mapping components
• parsing components would need to compare those labels to the map it uses
