I am using JIRA Portfolio (Server 3.2.1). View settings such as grouping, field columns, sorting, etc., revert after several days to a week, back to the default settings which include Target Start and Target End. What is causing the view settings to revert back to defaults periodically, and is there a way to prevent this from occurring? We set the portfolio view with several custom fields and also view settings to sort by a certain field and color. I'm aware we can share a read only view which has the saved settings in it, but still the view for the owner of the view, reverts back to defaults after 4 - 7 days. Occurs with both Chrome and IE browsers. Browser settings are configured so it does not delete cookies.
