XLF double target

Hi,

I've just finished working on an XLF file in Trados 2017 (note : I had to open and translate it as a single file, wasn't able to create a project for some reason) and when I finalised it I realised that the generated text had both the source and target languages in the same file...which I definitely don't want! I only want the target language. Can anyone tell me how I can acheive that ?

Thank you so much for your help !
