Umap key of description not working


I am asking you for help because the key of description which I enter in the general settings works in edition mode but never in consultation mode.
In editing, everything works at registration, but when I refresh the page, the label key is replaced by the layer name.

The map in question is :

Here are two files that illustrate the problem:

  • umap_calque: the label key that appears
  • umap_name: the desired label key that does not register in the general settings (several unsuccessful attempts).

    Where does the problem come from? How to solve it?
    Thank you
