In practice the technology does not keep duplicates on the bases of same source but different translations.

However this can be overwritten in may ways depending on workflows: 

• When confirming a segment users can "Add as New Translation" and allow "duplicates"
  
  
  
• When using Batch Tasks, users can opt to "Add new translation units" and allow "duplicates"
  
  
  
• Importing of SDLXLIFF/TMX directly into SDLTM  users can opt to "Add new translation units" and allow "duplicates"
  
  

Typically, uses start relying on TM metadata / fields to help isolate and promote segments based on what they deem are likely to be successful criteria

Example. Client A, Client B and preference is on Client B, by using filters when looking up translations

There is also an option to prioritise segments based on date

I hope some of this helps

Dear Lydia, 

thanks for your explanations, however, in our case this "error", if we can consider it as such, persists. Have a look at the following example:

Step 1: after pretranslationthe TM gives me a 99% match translated externally (green) in 2022:

Step 2: I revise it and replace one specific term and confirm (CTRL+Enter):

Yesterday I receive the recent version of the docuemnt, I run the pretranslation process, and, as you can see, both examples appear in the memory.

True, I have the "Show most recent translations first" box checked. But "show" is not "apply", so , when the documents are huge (this one is 133 000 words), the risk of applying the wrong translation because of these duplicates is very high.

So, after your reply, I checked on the shortcuts (because the CTRL+enter option in our case could correspond to the Add new translation option):

So, the Ctrl+Enter combination we use is not supposed to add new segments when we make changes in the translation results....

Any ideas of how to fix it? Or is it a bug (I have Trados 22)? The only thing I personally do (and I ask all my collegues to do the same) is to delete those incorrect segments manually. But then...new ones appear on a daily basis generating more confusions and mistakes....

Best regards!
