A caveat: I don't own the game.
Looking at the videos posted here: https://www.thegamecrafter.com/games/desolate
It looks like the crate icons on the Conflict cards are of different size. There are conflict cards with a small crate icon and others with a larger icon. The larger crate takes most of the square space which it is in.
If you look at the playthrough video, freeze the video at 01:26, and you can see the difference in crate size of 2 conflict cards side by side.
I hope this helps.
