Redmine

I created top issue (Main feature) and one child issue for the top issue (feature 1).
After that, I set "Spent time" for the child issue (feature 1) to 0.5 hours (or 1 hour, or 5 hours . . ).
Issue report for the Main feature shows recalculated values for the spent time (pic. 1).

main_feature_issue

Project's Issues report shows non-recalculated value for the "Spent time" column of the Main feature. It shows 0 hours but have to display 0.5 hours as sum of all spent times for all child issues. (pic. 2).
