Box caption - empty space

[marcellosaputo]

Hello. Still your help. In my photos of www.meravigliosamenteonlus.it, the box of the caption and then the title of the category is set to three lines of writing (and it's okay). Between the third line of writing and the bottom edge of the entire frame (box image + box caption) there is empty space (as if it were another line). How can I delete this blank space? Thank you

Hi, I don't see any gallery images on the site?
