Adding relations to other tasks also does not display a finishEnd of the deletion date Begin of the deletion in the milestone. 

It is unclear what effect toggling "manual scheduling" has on anything here - the checkbox appears to do nothing at all.

### **Expected Behavior**

I expect that I should be able to either set a finish dateEnd of the deletion for a Begin of the insertionMilestone (and not a start and a finished date)End of the insertion Begin of the deletion milestone, or it should be inferred from the related tasks. Neither of these appear to be possible at the moment.End of the deletion
