Walkable paths only occurs horizontally on 2D scene

Hi, I’m using Orthello 2D framework with A* pathfinding and unity v4. I’ve setup a 13x10 tiles consisting of walkable and non-walkable. I’ve also setup the AstarPath, sizes, dimensions, etc. and it looks like this.

Here’s my inspector tab

The problem is on the walkable nodes, the connection (thin line) is only made on horizontal tiles only. There are no vertical connections and my AI can only walk horizontally…

How to make the connections appear horizontal and vertical? THX b4

Note the Max Climb setting. Since the Climb Axis is set to Y, and the distance between nodes are greater than the Max Climb value, no connections along the Y axis will be generated.
