I'm actually having a similar problem as well, although my PPU is set to 1, and my Ortho Camera Size is at 72. Mine is somewhat less severe, as it seems to be only chopping off the bottom row of pixels, but it's still an odd issue.
They're all set to Single. Here's a image of my attached settings, although I think the problem isn't with the sprites but more some weird subpixeling with the camera. (The image also shows my Sprite Import settings as well.)
Weird, it might be the camera, could it be that the object isn't on an integer value, if so the camera might be doing something unwanted with the subpixeling
