Rezising problems

Hey,
I’m having trouble when dragging my tiles. They tend to snap anywhere but where i want. Sometimes it works but usually there is atleast one tile that just doesn’t want to cooperate. Have a look at my screenshots below. Obviously the photo would be a perfect fit bottom right, but no it snaps wrong every time. Any idea of what the problem is?
I’ve disabled the jetpack photon thing. Working in chrome if it is of any use.
I really like this plugin but this issue is driving my crazy, i hope you can help.
All the best!
