Issues are not shown in Backlog and Kanban within one project

[Dylan]

As the pictures below, in "Backlog" there are 64 issues, and in "Kanban" there are same amount.
But I have already created 122 issues as shown in "Issue". 

No filters, no sorts, the data is not synchronized. Why does it happens?

Hi @Dylan and welcome to the Community!

The issues you don't see may be done or in a status that is not mapped to column on your board. 

An important piece of information just fell off your screenshot: is your project team or company managed? If it is team managed, the root cause can be either of both things I mentioned. If it is team managed, I would mainly look at the number of done issues in your project. These get hidden from the board automatically after - I believe - 2 weeks.

That also reveals something that is good to know: while your issues may be hidden from the board after some time, you will always be able to search from them in the issues view.

Hope this helps!
