Watermark only applied on a single size

Hi,

I have selected Manual application of Watermark. I also selected ALL types of image size including Full.

Then I go to my Media library, selected the specific image that I want the watermark to be applied, in the batch I select Apply Watermark and Apply.

Only the small image size have the watermark now. The Full size image do not have it.

Am I doing something wrong?

Thanks!!!
