When selecting the option “Fit entire image resized to min height”, the images on my event pages are getting cropped at top/bottom instead of resizing to fit the box.

The min height I have specified is 400px. If you look at this example you can see the cropping: https://dystopianstories.com/events/hastings-book-festival-writing-competitions/

I created this mockup of what I think this setting should make the image look like: https://dystopianstories.com/wp-content/uploads/2025/06/Octo-Books-Child-Friendly-Writing-Competition-resize.jpg

On some pages, the resizing does seem to work, but I do not understand the logic to it. For example, on this page the featured image does resize to fir the box instead of getting cropped: https://dystopianstories.com/events/tennessee-williams-festival-fiction-contest/

Is this a defect? If not, can you explain the difference between the settings “Fit entire image resized to min height” and “Scaled cropped image to fit the full box” are?

Thank you for your help.
