Two Lightbox overlap?

I am seeing 2 light box one top of another one: https://webcolor-001-site6.itempurl.com/events/6th-annual-james-faucett-iii-sickle-cell-awareness-5k-1-mile-walk-run/

I installed FooBox and enabled it but when I click these image I see 2 lightbox. Thumb link is set to “Full Size Image (Lightbox)” and if I change this I won’t see any lightbox.

The page I need help with: [log in to see the link]
