Clearlogo and Clearart not appearing

Hello, I have an issue, I scrape my movies and the shows with local informations only which are stored on my HDD. The posters, fanarts, banners,… are displayed even if my HDD is disconnected but if I disconnect my HDD, clearlogos ans cleararts are not displayed. It’s a problem because when my HDD is connected all the artworks appear immedialty except clearlogos and cleararts which take few seconds to appear. How can I fix that ? I have this issue both on my android tv and windows pc.

Thanks
