## Description

### Steps to reproduce

1.  Have two types of work packages:
    
    1.  Type A - without Automatically generated subjects
    
    2.  Type B - with Automatically generated subjects

2.  Have a work package of type A with child 1 of Type A and child 2 of Type B

3.  Verify that the parent date scheduling mode is set to automatic

4.  Change the date of child 2

5.  Change the date of child 1

6.  Change again the date of child 2

7.  Change again the date of child 1 

### What is the buggy behavior?

  - The parent date doesn't update in step 4 and 6
    
      - after step 4 it still is unset
    
      - after step 6 it still is the same as after step 5

### What is the expected behavior?

1.  The parent dates should update every time

### Additional information

  - in the Gantt chart module the parent actually shows updated dates, but this is due to a different display logic
