Tabs gallery grid not working

Iv created a Gallery in a Tabs Menu in the Portfolio section of my site. inside each Tabs Pane iv placed Div Block that iv turned into a grid. Each Div Block contains several Lightbox’s. There was an empty space on each grid in the top left corner. I filled it by placing the position to manual. The trouble is that now I can no longer hover over the first item of any of the items in the grids. the Filters Transforms and Transitions are no longer working for the first item in the grid and I cant click on them.

Heres a link to my site
