do you have a solution for that?

I'm using WPML and I translated one event, by pressing the "+" and copying the content from English and later tried to overwrite with English content both times with the same result.
The event was shown in each language (when I had English it was English, when I selected Greek it was Greek) but each was a different event.
So each had 10 seats (so 20 in total) instead of 10 in total no matter the language.
Not sure if I make sense, but do you have a solution for that?
