Why does empty task shown as completed in sidebar?

HI not quite sure why an open task like this 
<img width="133" alt="image" src="https://github.com/user-attachments/assets/24ffbb4f-927b-4267-9bf0-d06a8304b776">
is rendered as completed on the unplanned tasks bar?
<img width="162" alt="image" src="https://github.com/user-attachments/assets/10b83c31-8530-4540-9b75-1f06b71dad91">
