Hello,
I located the worry.
For example, you noticed that the list (seen from your screenshots) had only one choice, which did not make sense. There should have been several choices.
What happened is that when you modify an existing list, the changes (Addition for example) are not saved and in my case, not only I added an item but also I moved it to the second position of the list.
After registration, the new item was not seen and all items placed after the new item were deleted.
I tried to completely redo the list, and at that moment it works.
So the conlusion is that when one intervenes on an existing list, the new item is not registered, but in addition if one moves it to insert it to another rank in the list, all those who are after are erased.
We must redo the whole list.
Best regards.
Eric
