Our work section

Hello,

I am setting a website and my the section Our Wors, where it should display the pictures is not working properly.
I have 2 categories , but it doesnt show pictures in one of them.
All the pictures for both categories shows in the tab ALL.
It takes a lot of space in the home page, plus it does not look good.
I would like to have them separated by category and only show 2 rows in each one of the categories.

Could you kindly help me out?
Best Regards,
Ana
