Cracking theme but slideshow renders featured image weirdly

Hi mate,

I’ve been using your theme for https://finbytes.co.uk and I truly think it’s beautiful and amazing and although I’ve only recently installed your “lite” theme I’m considering buying the full version.

I have an issue, for my latest post, the featured image is in exactly the same dimensions as featured images used for previous posts, however in the slideshow on the home page the featured images gets rendered as a square and is so much bigger than the other featured images in the slideshow.

I’ve triple-checked that all the images in the slideshow have exactly the same dimensions and gone through all the settings, but it just won’t display correctly.

Could you please tale a look and help me with this?
