Hi there,
it seams to me, that deep linking is not working like expected.
The first and the last items are not shown. If you call these items, you will see the whole grid.
You can prove this on their own site too:

If you follow their link in the tutorial (Point 3)
https://www.themepunch.com/faq/deep-linking-essential-grid-lightbox/#group-3
you will see the same page as before.
Same issue with the first item:

Only the second one is working:

This reflects the behavior on my site. First and last item is not working. All in between are.
A bugfix or workaround would be great.
