Hello, @Nanda_Untari, welcome to the forum! Some projects require running a mandatory QA check. You can find information on how to perform one here.
Once all segments have been confirmed and all QA check errors either corrected or ignored (if applicable), you should be able to complete the task!
If you are still experiencing issues, you can contact your project manager by email (should see the address in the project information) or tagging them here.
Hope this helps! Have a nice week
