Issue in child table list filter option

I am experiencing an issue in ERPNext where the filter option for the child table list of details was visible in the past, but it is currently not visible. I have checked role permissions, cleared browser cache, and reviewed any custom scripts or customizations, but the problem persists. Any insights or suggestions from the community would be greatly appreciated.

I have uploaded the screenshot of the child table which is working, but for now that filtering option is not visible
