Hi Lolita,
Sorry to hear that you are facing troubles with Adobe Stock.
For better customer experience, faceted Search filter options have been introduced which ensures that we only show filters that apply to the search results set.
Additionally, the user can now specify “Asset Type” (like Images, Videos, Templates, etc) directly from the filters panel and the panel will update with relevant filters based on their selection.
After Faceted Search – Only filters that will display results are shown (e.g. when the Premium filter is engaged first, the vector subcategory is hidden since vectors are not a part of the Premium collection). Also, the 3D assets and the videos do not include a subcategory, however, when you click on "ALL" and " "Images" under the "Asset type", you still have an option to choose whether you want a vector or a JPEG file.
Below is the screenshot:

Feel free to update this thread in case of any additional questions.
Regards,
Twarita
