I've changed the configuration of our Kanban board from swimlanes based on assignees to swimlanes based on queries. It will be fine for a few hours, and then it reverts back to the old assignee configuration. The queries themselves are still saved, I just keep having to go back into board settings and change the dropdown again.
Has anyone else seen this behaviour? I cleared all local storage for the site, but I'm still seeing this happen both in Safari and in Chrome.
