How to delete a word in one language ?

Hello !

I would like to know how to delete a part of an entry in one language in the database.

For example, if I have one word  in German and two words in French for it, and I only would like to keep one in French, how do I have to do it? I want to delete the one with the status "Superseded",.

I can edit the entry in French by clicking on the pen icon, but as soon as I want to delete one of the words completely, it doesn't work.

Thank you in advance for your help :)
