(Noob) - Getting stuck Jumping over colliders?

Just messing around with 2D side scrolling to learn Unity. I'm having an issue where the player tries to jump over a cube with a box collider (both have rigidbody) and if you try and jump to close you kind of get stuck on the way up.

Is there a way to just have the player able to get over something like this without having to backup or spam the jump button?

Here is a gfy example of what I mean. The character and box both have rigidbody and box colliders.

As you can see, the player gets kind of stuck and ends up sort of climbing the box instead of just jumping to the top of it.

Thanks in advance!
