WP Smush Pro doesn't resize original images

Hi,
I've set up WP Smush settings to resize original images as well as all other image sizes, to a maximum of 1024x1024px.
Unfortunately, the images are well smushed (in their weight manner) but their dimensions remain as they are, for example: 5312x2988px.
I've set a grant access for your support.
Thanks in advanced,
