Gantt Chart - Milestones not showing

Hi All

We have recently set up the Gantt chart on our vault and I have it working with projects, phases, Activities and recurring items, however, the milestones aren't showing in the Gantt chart.

I have followed the instructions (Feb 2 2018) 5.7 for Milestones and when get to the instructions to select the milestone from the view I can see the milestone.

Has anyone experienced this when setting up the Gantt chart and if so how did you resolve this?
