The task is completed but the task in the UI graph keeps running, even after refreshing the browser page. This bug has been happening quite often lately.

Is this in cloud or oss? If oss, what version?

Cloud version !

I’ve encountered this bug as well on the OSS version.

I released a change today that I think might have fixed this, but I wasn't able to reproduce so I'm not sure. Can you let me know if you see this again?
