Why are some columns missing from my ticket views?
When creating a custom view, you have the option of adding up to 10 columns to identify specific data to preview ticket information. If you deactivate a ticket field that stays in your view conditions, the column will cease to show up in the view. Similarly, if you deactivate all ticket fields in your views, your view will only contain the Status column as shown below:
To resolve this issue, go to the Admin ( ) icon > Manage > Ticket Fields > reactivate the missing ticket fields.
Alternatively, you can replace the columns located in your view to a field that is active.
