In Automation 8.18.x & 9.0.x, pages with a "Manage columns" button (E.g. Service Broker -> Deployments or Assembler -> Resources) do not save the selected columns when a user navigates away from a page and then back to it. The displayed column settings are always reset to default values.
Automation 8.18.x
Automation 9.0.x
In current Automation versions, the "Manage Columns" functionality is only applied to the current page view.
Saving the "Manage Columns" settings for each user is tentatively planned for release in Automation version 9.1.
