Assumptions
Automatic schedule correction is enabled in the Gantt chart settings.
Issues
The start and end dates of tickets are changing automatically.
Specific Example:
Start Date: 2023/10/18
End Date: 2023/12/4
↓ * Automatically adjusted without any manual settings
Start Date: 2023/9/18
End Date: 2024/2/5

No ticket has an end date set for 2024.
Actions Taken:
Try to modifying exact date on the Gantt chart.-Didn't work
Modifying dates of parent/Child tickets and linked tickets.-Didn't work. Even though once I modify the date, it changes automatically.
Turning off automatic schedule correction →It works, but inconvenience arises due to the lack of automatic correction. Therefore I would like to understand the root cause.
