Arrow has a gap towards the Node

[sarahm7]

hope you can help, i'm struggling to move the arrow closer to the node here below. i can't seem to make it look better at this point

here's my settings

     edges: {
        smooth: {
          type: 'cubicBezier',
          forceDirection: 'vertical',
          roundness: 0.9,
          enabled: true
        },
        arrows: {
          to: { enabled: true, scaleFactor: 0.5 },
          middle: { enabled: false, scaleFactor: 1 },
          from: { enabled: false, scaleFactor: 0.5 }
        },
        color: {
          color: '#ffab40',
          highlight: '#2B7CE9'
        },
        width: 2,
        selectionWidth: 2
      },
      layout: {
        hierarchical: {
          direction: 'UD',
          sortMethod: 'directed',
          levelSeparation: 200,
          nodeSpacing: 200,
          treeSpacing: 150
        }
      }
