A* Pathfinding jagged path

I’m using the A* pathfinding package for my game. The path that is generated is very jagged and results in the character moving in a zig zaggy way. I’ve applied the simple smooth modifier but it only smoothens the jagged path and does not straighten it out at all. I’m not sure what else to do. Help is appreciated. Thanks.

Haven’t used that package.

Can you increase the weighting of diagonal paths and see what effect that has?
