Good afternoon, 

I am trying to export an xlf file from Trados but each time I try I get a message 'The ID '1' is a duplicate across siblings'. 

I have opened up the file to see the structure and there are multiple mentions of 'id=1' in the file however this is the case in another xlf file that I've recently exported so I can't see how this can be the problem. 

I've run the tag verifier and fixed any issues with tags but the issue still remains. I've also tried creating multiple Trados projects to see if the original project had just become corrupt. 

Is there anyone who can advise on how we might be able to fix this please? I'd like this to be resolved by tomorrow if at all possible. 

Thank you very much. 

Sarah
