After delivering a milestone shape, it shows as incomplete

[copper loom]

It can't be delivered again, and it unlocked the next milestone, but the half circles are still pinned on my task hotbar.

The first and second half-circle tasks are different. Click the shape and examine it, the second one has pins underneath.

I understand that, I'm just confused why it unlocked the final shape

also, they both have pins, the second one just has more pins
