I have a notification that someone edited my translation (boring!) - but the name provoked my curiosity and I went to look, and on looking found nothing but my original translation. No other versions. I'm perplexed. What's going on? What exactly did you do to it????
OK, now this is getting weird. In an unrelated incident I had another notification for another translation on another article. I followed the link that you get saying 'x edited your translation'. It takes me to a page on which I had done translations and a bit of text I think I did edit. Only it gives me a blank open window in which to insert a translation as if no one had ever translated it.
This could happen if there are repetitions in the uploaded text. In the English-German Duolingo it happened sometimes to me with an article about a type of mercedes. In this uploaded document there is the same text for 3 times. Every time someone edited, I got a notification and when I went to the text I found an open window (after a while I saw that it was a repetition of a sentence on top of the document, a sentence I really have translated and which was edited)
