Thanks for the file! The bug is reproducible. It is already fixed in the upcoming GP 3.4 and I will backport it to the next maintenance update to GP 3.3

By the way, thanks for sharing a big project with many tasks. I see that GP 3.3 has severe performance issues when working with this project. Those issues are also fixed in GP 3.4, and can be backported to GP 3.3 as well.

Update 3311, which fixes this issue, is out. It can be installed on top of GanttProject 3.3 via the Update Channel.
