描述

Kibana version: 7.14.0 BC3

Elasticsearch version: 7.14.0 BC3

Server OS version: darwin_x86_64

Browser version: chrome latest

Browser OS version: OS X

Original install method (e.g. download page, yum, from source, etc.): from staging

Describe the bug: If the field value is "null" or empty - we display an empty row in filter panel for values. This blends into the background and I am not sure if the UX is giving the user that message.

Please note I used kibana sample logs for this and the field I am filtering on is extension.keyword

研究方向
The issue reports that null/empty field values display as blank rows in the filter panel, which is confusing on both light and dark themes. The screenshots show the problem in Kibana's sample logs for 'extension.keyword'. To fix, locate the filter panel component in the Kibana codebase (likely under 'src/plugins/data/public/ui/filter editor' or similar). The fix should display 'null' or empty placeholder text instead of an empty row, ensuring proper styling for both themes. Check the CSS for the filter value list and add a class or condition to show a readable value.
