Application form. The location map can't be changed when editing an existing application

[rbejar]

Describe the bug
Modifying the location map in an existing application fails.
It also fails to report the error: it shows "items updated successfully".

To Reproduce
Steps to reproduce the behavior:

1. Go to https://sitmun.github.io/admin-app/#/dashboard
2. Login.
3. Choose Application on the left side.
4. Click on the pencil icon (edit) the application with id 15.
5. In the Location Map drop-down choose "Mapa de situació"
6. Click on the save button.

Expected behavior
It should update the location map of the application 15.
But it does not. It briefly shows a red box, but it ends up showing "items updated successfully". However, if you return and edit the application 15 agian, the location map has not been changed.

Desktop (please complete the following information):

• OS: Kubuntu 22.04
• Browser: Vivaldi.
• Version: Latest.
