middle section of featured home page row acting up

I’m not sure I’ve observed this before, but my client is using melos dark free version, and brought to my attention that the middle image of the home page featured row is showing at half the vertical dimension suddenly. I tested with the melos parent theme and it is doing it too. Did this change as a visual feature to the theme, or is this a bug with the latest update to the theme? I haven’t had to revert to earlier versions of themes before, but where would I go to access an earlier version of melos dark to see if this is an update problem or not?
