Disappeared tasks

[Svetlana]

Good afternoon!

The following situation happened: the tasks were in the project and on the board, then disappeared from there. I can find them only through the "Filter" tab in the extended task list. When I open the task, there is a note that the task belongs to project X. And in project X it is missing.
Please tell me how to return the task to the board and make sure that they will not disappear in the future?

First, look at the board filter(s).  Go to board configuration -> general and read off the definition of the filters there.

For a Scrum board, it's just the board filter, but for a Kanban board, you'll also want to read the "sub filter"

Do your "missing" issues match the board filter?  (And if a Kanban, do they also match the sub-filter, which is there to hide "done" issues)

Secondly, go to the "columns" configuration of the board.  Are all the status mapped into columns?

Hi,

An issue belong to a board based on the JQL filter associated to this board. So first look at your board filter to see if this issue is not excluded from it.

In my case, filters are not installed on the board. Tasks were disappeared not only from the board, but also from list of tasks and so on.  They are present only in extended task list.
