Task not deleting

[Mark Fowler]

The following bug applies to multiple tasks, not just one. When I finish a task, I mark it as completed, and it disappears from the list. However, when I search using a similar alpha string, the completed tasks reappear and are not marked as completed. I have deleted all completed tasks using another Google Tasks app that lets you delete completed tasks, and the tasks still appear as incomplete in Google Tasks Fullscreen in search.

Hi, I believe that after you check off a task, it may be still searchable, but if you reload the fullscreen app, wait a few seconds, and search again, the same tasks shouldn't be searchable anymore, because there's a step to auto prune the search cache after page load, and the cache only stores unfinished tasks.
