Redmine

Here are some of my issue statuses:

Activity TBC is the status per default, and no % done is associated.

These are my parameters in issue tracking:

- Issue done ratio is associated to the issue status
- % done is calculated from subtasks.

Now I create an issue "t1", with "Activity TBC" status (no % done associated):

Then I create a subtask s1 with status "In progress 40%".

My t1 task looks like this (all fine):

Then, I manually change the status of t1 to "Started 20 %". Everything is still OK, % done of the parent task takes precedence over subtasks:

But Now, I want to change the status of t1 back to "Activity TBC", with no % associated:

Expected: % done of t1 should be calculated from its subtasks (here 40%) since no % is longer associated with it

I have encountered this problem with redmine versions 3.x (also with redmine 3.2.0)

My production configuration:
