Can’t add watermark on image

Good morning,

I have a problem with the watermark, one day it didn’t work anymore. Now when I go to the media library I see this: “Image watermark: Bulk watermark is only available in list mode, under the dropdown Actions in bulk. You can enter List mode or hide this warning” and I can add the watermark only in list mode, but before I could add it in every image in the media library or when I added an image on the post. Can you help me?
Best regards
