Tip #1:
Editors should always double check if proper names, prices, references and locations in source and target are the same and, if they're not, they should change them according to the the original entity in the source text.
Examples:
[source EN] Good morning Elisa,
[wrong entity] Good morning Camilla;
[source EN] I've refunded you $500;
[wrong entity] I've refunded you $5;
[source EN] You need to go to Milano Malpensa airport;
[wrong entity] You need to go to Milano Milano airport;
[source EN] The reference number for your query is XCV456;
[wrong entity] The reference number for your query is 383BF.
