This is caused by the image capture. Take a look at the 1st image at the top left. It says “$40” in the top centre (white on black). This is the caption of the image that is apparently displayed on the image.
The Mesmerize theme you are using is responsible for this. This does not happen with a standard theme such as TwentyTwentyFour.
A quick solution could be:
body .wp-block-image figcaption {
top: auto;
}
