xViz Community Milestones are hiding under the vertical bars_ Xviz Gantt Resource Chart

Greetings!

The Milestones in a xViz Gantt Resource chart are hiding below the the Timeline Bar, I would highlight them on Top of the bars, check the attached Picture for more details.

When, A dark colour is assigned the Bars , the milestones are no visible. Please help me with best solution.

Pentagon & Diamond are the milestones on the Bar.

Thank You.
