Watermark not removed

Hello,

I have deleted the logo watermark on this product image (Moustache Lundi 27.1) and it worked.

https://en-velo-simone.fr/wp-content/uploads/2024/07/meilleur-velo-electrique-en-velo-simone.fr-Moustache-Lundi-27.1.jpg

But when I uploading it on a page, there is still the logo watermark : https://en-velo-simone.fr/produit/moustache-lundi-27-1/

I have deleted my cache. What else should I do to not having any more the watermark ?

Thanks a lot
