MIN Start Date is not actually the earliest date of subitems

Hello,

I contacted Wrike Support and was told this behavior is intentional, but I believe it is a bug - or, at least, very confusing and not matching with what Wrike describes for this feature.

When turning on the automatic calculation for dates for a parent task, the "Start date" does not show the earliest date of the subitems (when subitems are milestones, without a start date). Rather, it always shows 1 day later. 

For example (see below): "Subtask A" has a Due date of 9/1/25. The "MIN" Start date for the parent, "Parent Task 1", is 9/2/25. If users are managing schedules in Wrike and depending on the automatic date calculations for parents, they will miss the first milestone by 1 day. The "MIN" or minimum date is not actually the earliest date. 

What's also strange is that the automatic date calculation for the project (TEST) actually shows the correct earliest start date, 9/1/25. So at the project level, the automatic date calculation actually works correctly. The task calculations should be consistent with this.

I know there are workarounds for this like adding dependencies, adding start dates for the subtasks, but if we want projects structured as above, I believe the automatic date calculations should still work. Could this bug please be fixed? Thanks!
