Okay Alex. So if the problem was because the API works differently depending on the language, then the saved result in the table would not be the same whether I was in French or English at the time I saved. In that case I would have understood.
But that is not the case. Whether I am in French or English at the time I save, the recording is the same. City + Region + Country.
The problem is only at the display and if I understand what you are telling me, when viewing the field, unlike the map, it takes the stored information.
It seems that when I am in French he "forgets" to recover the city which is nevertheless present in the table. So it's surprising why?
