Character stick to bottom of ground static objects. How do I fix this? Hello blender stack exchange people!
So this is a simple problem, but I haven't found a solution yet. My character is sticking to the bottom of the ground cube. I'm making a platformer game (image below) and the collision cube for my character sticks to the bottom of the collision cube for the ground (invisible) when I am pushing the up button.

Here's what it looks like in object mode:

That's all I can say about it... Please tell me if you need more info and what it is. My character has character physics obviously. 
I need to fix this because if the player doesn't make the jump, the character should fall instead of traveling under the cube seemingly floating through the air. Thanks a lot!

I found a solution that works well enough for me. Basically, I made the ground cube skinnier and added planes that extend to the death plane (the plane that restarts the scene when you fall off the edge and die).

Unfortunately, this doesn't explain why it happens, so I can't find a more reasonable solution. But maybe someone can explain that to me.
