One of my categories doesn`t show its posts.

Hi!
I hope you can help me with this plot…

Theme that I use: lifestyle Revolution

I have 7 categories in my site, all of them are shown at “HOME”, each one shows 3, 4 or 2 post at “home”; 3, 4, 2 post about 10 or 15 in total. But one of these categories doesn`t show the rest of its posts.

What could be happenning?
You can check it up at https://www.vivolau.net, “TECNOLOGIA Y SALUD” category doesn`t unfold, to clicking on, it send me to HOME.
Thanks in advance!
