Can't click link post in Feauture Slider

Hi all,
As title above, I try add posts to Feature Slider, but in front page I can’t click link of post (button Next, Previous is ok)

* Mobile browser -> working ok
* Desktop browser -> bug

I think this issue is bug of theme, because I checked this in demo link and it same issue as me.

Please help me to fix it.
