Issues no longer visible on board, how can I debug this?

[Karsten Meier]

Hello Jira Fans,

I know quite a lot of the jira classic projects, but only played a little with the next gen projects.
A different team has set up a next-gen board, and a member now said that the board no longer showing all their issues. They said they now used the raodmap-feature instead the board for some time now.....

I checked, and found with the filter that 16 issue have the status "IN Development".
But the board, I see only 1 issue in the column "IN DEVELOPMENT".
I don't see much I can configure. Waht can be the reason, and how can I further analyse this?

@Karsten Meier is it a Next Gen Scrum or Next Gen Kanban?

Good Question. Looks like Kanban.
In the feature-settings, I see that "Sprints" is disabled.

Also, I found a least some of the missing issues in the backlog,
even though that the issues got a status of "in development".
