Backend search not updating data

Hi, I am having troubles with the property search in the backend, the one that is available in “all properties” section.
I went to settings, changed values for a specific attribute (changed search input and data entry values).
Everything works fine in the property detail page, I can edit single posts, everywhere it works fine BUT in the section /wp-admin/edit.php?post_type=property&page=all_properties
Here I can see all the old values of the attribute I changed.
What can it be?
Thanks
Simona
