One columns from the kanban board is not showing

[Arshia Akhtar]

All the tasks under it are not visible. The  column is not showing without any change in settings. Although if I I  open from link they are there in JIRA but hidden somewhere. How to get that column back with all the tasks under it? Please guide Thanks

Could you provide some more context?

• What type of project is it (team or company managed? 
• What does the configuration of the project look like?
