Here is a MWE. The \addmilestones that are commented out in the MWE are the problem. The actual dates that I need are presented at the end of each \addmilestone command. Also the color of the bubbles should be varying shades of red commensurate with the size of the bubble. Small bubble =light red, biggest bubble = blood red.
