'late tasks' dashboard problem in 1.5

[woland255]

Good day to all.
May be this is not a bug but my misunderstanding... When in 1.5 I create new task in past (due day), it is not appear in "Late tasks" dashboard. But some older tasks, that exists before upgrade appears here. Same thing if I create task in the future and after time it becomes "late".
Is this a bug or some my misunderstanding?
Thanks a lot.

Some additional information. When  select workspace where new task was created, "Late tasks" dashboard starts to show correct information. But when I select parent workspace, this information is lost....... It somehow "loose inheritance". Why?
