hide "data queried" when there was no data queried

## problem

even when no data is queried, this dropdown still shows up:

<img width="2382" height="1084" alt="Image" src="https://github.com/user-attachments/assets/2dc0c90a-def6-4463-bb6a-0e6c1b47d81d" />

## suggestion

remove it if there is no valuable data in the dropdown
