Portfolio bug question – Unicon theme

Hi Minti theme

In the lasts days I found out my website has a bug on the portfolio section.
One of the images (The Kay Kronicle) doesn’t have the same behavior as the others. The size is the same but what you see in the page is different.
I already tried to duplicate one portfolio and change the images but didn’t resolve.
Can you help me?
