Tablet & Mobile size adjustment

Hey

So i have 3 pictures with the plugin on this page. All is good but when i look at this page with tablet view then he 3 picture just get big and they don’t stay with 3 next to each other.

I know of the button to the settings of tablet view but it doesn’t do anything.
click here for the settings.

I wonder if I’m missing something. Because when people look at this page from a tablet i don’t want 3 giant photos below each other.

Thanks
