Copying a page duplicate tasks

Issue Summary

Working with tasks on Confluence is a great way to keep tracking our daily job! Sometimes, on an existing page that already contains a determined format, we can copy it and then just change the tasks' description, in order to make our life easier - though, doing this is currently making the Task Report macro to behave unexpectedly.

Steps to Reproduce

1. Create a page called Report and add a Task Report macro;
2. In the same space you created the above page, create a new one called Tasks;
3. Add a few tasks with random names there (3 tasks are enough) and publish the page;
4. Copy Tasks;
5. In the Copy of Tasks, change the text from the three tasks and publish the page;
6. Go to the Report page.

Expected Results

The Task Report macro shows all the distinct tasks from both pages;

Actual Results

The Task Report macro duplicate the tasks that got their name changed on the copied page. It also happens in the tasks session, on the user profile.

Notes:

• If on step #5 you actually remove the tasks and publish the page without any task, in the report macro/user profile tasks, they are shown with the old name in the copied page.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
