Task already done,but it is still shows pending

On 6th June,2020, I have been allocated the task for installing and configuring Postgresql. I have already completed the task successfully. On 8th, I have checked it was pending. Again I have completed the task successfully. After reloading the page it is showing again pending. Please solve this issue.

Sorry about that. There seems to be a bug. We are working on a fix.
