Watermark doesn't work for all images

Hello,

The watermark doesn’t work for all images, some images show pixelated without watermark, some show small images, and other show the watermark image.

40% off all images are watermarked, 40% are pixelated without watermark and the other 20% are small images without watermark.

I have checked the Watermark enabled but I didn’t see all images with watermark, why? I want that all images to work properly with watermark not just a part of them…

I look forward to hearing from you, Emilian. Thanks for this great plugin but it is very bad that it does not work properly.

Thank you.
