[bug]: Default Value on combobox not working

[charlelisefouasse]

Describe the bug

Default Value on combobox is not working. There are 2 issues:

• Value is displayed in input instead of label
• Value is lost onBlur

See this video :

Capture.video.du.2025-12-22.11-25-48.webm

We can see "tre-flip" instead of "Tre flip" and value disappears when blur

How to reproduce

1. Have a combox with value != label displayed
2. Set a default value with item value (not label)
3. see that the input is filled with value instead of displayed value
4. focus field in combobox, then blur: value disappears
