Filter works but when selected there is no result response

Hi,

Filter work partially fine : there is only one filter who doesn’t work well and I doesn’t know why : https://www.loom.com/share/abb4ee77aa3d43bb9bcbc4403ceaa558?sid=46b742bb-2fd4-4964-8123-83011826216c

The filter is a custom field as the other but only this one shows number rsults in the filter but not in the result page.

Any idea ?

Thanks in advance for your help,
