Hi @Mariana Castañeda, 

When importing from bilingual document there is the option to Include or exclude segments based on translation status (confirmed , untranslated etc). If I am not wrong, the default is set to import the confirmed segments. Maybe retry the import and please check which options you have ticked. 

Also during the import stage, there is the option to select if you want segments identical to the ones you have already on the TM to overwrite them or create new ones (which might create duplicate TUs). So there might be some some segments that have overwritten your TUs . To check if this is the case please retry adding the SDLXLIFF either in a blank TM and see if the same number of imported Tus appears. 

I hope the will help. 

Best regards, 

Loredana

Thank you for your response Ana-Loredana. I did checked that all options of segment status were permitted to be imported so as you said, I created a new translation memory... so I guess all TU's are finally stored.
