Correction of a bug on the website

On the website
https://yellowcolibri.ca

In the section Portfolio/Events tab does not work the button "See more videos"

Should work so, how does the tab "Promotional":
Displays 6 videos, when you click on "See more videos" opens another 6, and so on.
And the button disappear when open all video.

Now Events added more 6 video.

Also in Portfolio/Animation is not lost, the button "See more videos" when opening all videos.

Really need to fix!
