User interface: user cannot assign a wastewater structure when importing data

[kandre]

Describe the bug
On the user interface, when multiple wastewater structures are suggested, the user can select one of them, but can not assign it before importing data.
Indeed:

• the assign button does not work when clicked.
• the select map feature button does not work when clicked

To Reproduce

1. Import an xtf file of VSA-KEK manhole damages data from graphical user interface of qgepqwat2ili
2. Select an examination with a warning (on the left panel)
3. Select one of the suggested options (on the right panel)
4. Click on the assign button
   or
   4bis. Click on the "assign from the map button"
5. Nothing happens

Expected behavior
The assigned structure should be visible in the "Actuellement assignés" panel after using the assign buttons or the "select map feature" button
One can assign and de-assign structures.

Cannot confirm these issues. Maybe due to English project file instead of French project file. Further research needed.
