Overlapping image in gallery page

Hi Everybody,

I have a strange image repeat on a gallery style page for my company’s website.
The problem page is the second image on this link:

https://fhtdesign.com/work/wigwag-home-automation-suite

The first product we are showcasing, the second image in that set for some reason has a bar on the bottom of it (a repeat of the same image) that cannot be removed!
Changing the order of the images revealed to me that its always on the second image.

How do I fix it?

I hope this makes sense.

Regards,

Magnus
