Change in Portfolio Section?

Hello there, first I want to thank you for the great works on the theme development! The newest updates were perfectly fine, but there is this question I wanna ask about the Portfolio Section, it seems that now it displays differently not like it was?

The former display was pictures were displayed according to the category being clicked right, but now on my home page I can’t click the other categories in the section and all the pictures were displayed together (I hope I explain this correctly, sorry if I’m not clear enough).

To help you get what I meant, here is the link to my site:

You can see the Portfolio Section is not like it was/like in the Demo.

I hope you can give answers and help me about it. Thanks again!
