Step 1: Manually re-position your milestone markers.
Click on the text box of the milestone you want to re-position and drag it vertically to a new position as shown in the image below. This can be done for both milestones that are positioned above or below the time band.
Step 2: Click accept and choose Accept Manual Changes.
Once you have moved your milestone to the desired position, click the Accept button on the ribbon to save and to automatically create a connector from the timeband to your newly positioned milestone. You can see the changes in the image below.
