Updates & Changes

Hey guys, I have a question, where with all the changes I make in LEX, do they automatically update in Traktor/iTunes.
I made some changes, but when performing a “Check consistency”, the changes didn’t appear.
The question, do I need to synch it with Traktor/iTunes, or write to files within LEX.
