Task Report macro duplicates tasks

Issue Summary

The Task Report macro is currently duplicating some tasks depending on how its pagination is set.

Steps to Reproduce

1. Create a page called Tasks Page and add around 50 tasks;
2. Add a label to this page (abcd, for example);
3. Create a new page called Task Report and add the Task Report macro;
4. Configure this macro to get pages with the label abcd
5. Publish the page.

Expected Results

The Task Report page shows all the expected tasks with correct pagination for the exceeding tasks.

Actual Results

Sometimes, the pagination causes the tasks to get duplicated in the Task Report macro.

Workaround

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