Image in Frontpage Featured Section is wrong aspect ratio

Hi there, I do love your theme and I am thinking about purchasing the pro version. Most problems I can sort out…however, this one has stumped me. The Featured Image, which is set on the /jewellery/ page and is the correct aspect ratio on there, is the wrong aspect ratio on the Frontpage Featured Section. It only does this with this one image, the other two images either side are correct.

I’ve tried deactivating Site Origin; deleting the image from the server and replacing it; uploading the image with a different name and resizing it within WP all to no avail! I feel there might be an issue with the database, but I don’t know.

BTW I moved this image-page to the middle of the Frontpage Featured Section so it looked deliberate! Do you have any suggestions on hoe to resolve this issue?
