Can't edit 4th image of the basic template FV-28

I'm using the basic template and when I try to edit the text of the 4th image in it, when I click the text to change it, it takes me back to the 2nd image in the list immediately instead. I managed once to edit the text but I have not been able to do so again. The same happens for the iPad set. It's almost like it thinks both images are the 'same' (not sure if it's a coincidence the one it takes me back to uses the exact same layout - text on bottom, image on top).
