Welcome to the Forum @Arjen_De_Jong and apologies for the trouble here.
I can confirm this is not a bug but rather the current behaviour. Let me give you some context here.
By default, tasks that are first assigned to you are placed in the Recently assigned section. From there, you have the option to use the Today, Upcoming and Later Sections to prioritize your tasks.
For example, you can:
- Place tasks you’re working on today in the Today section.
- Place tasks you’re working on this week in the Upcoming section
- Place tasks you’re working on next week or later in the Later section
The ability to Mark tasks as Today, Upcoming, or Later is for your personal prioritization, and is only relevant in the My Tasks list. This means that these sections are not inherently connected to due dates, so unless you prioritize your tasks between these sections, they will by default remain in the Recently Assigned Section.
You can learn more about My Tasks in this Guide Article: https://asana.com/guide/help/fundamentals/my-tasks#gl-priority
I hope this helps clarifying but please let me know if you need further assistance! Have a nice day Arjen!
