Gantt – Change Milestone ‘Selected’ Color

0

Hi there, I am using conditional formatting to change the color of the milestone icon depending on the status (i.e. green for complete, red for overdue, grey for pending).  However if I click (select) any row, the milestone color changes to a red fill.  I don’t want the milestone color to change at all when I select a row, but cannot find where this behavior is defined.

I can only find this reference to color selection but changing it has no effect on this behavior

Anyone know how to change this, or even completely disable the row selection feature?
Many thanks
