Redmine

Hello,

I want to add new cloumn on Issues view (Issues tab). In Options section I choose the new columns and move this from Available Columns to Selected Columns. When I click Apply button, the Redmine shows the new column. But when I click Save button, I see Internal Error (Redmine 500 error) page.
I found this message in the log file:

ActionView::Template::Error (uninitialized constant Query::VISIBILITY_PRIVATE):
    17:
    18: <% if User.current.admin? || User.current.allowed_to?(:manage_public_queries, @project) %>
    19: <p><label><%=l(:field_visible)%></label>
    20:   <label class="block"><%= radio_button 'query', 'visibility', Query::VISIBILITY_PRIVATE %> <%= l(:label_visibility_private) %></label>
    21:   <label class="block"><%= radio_button 'query', 'visibility', Query::VISIBILITY_ROLES %> <%= l(:label_visibility_roles) %>:</label>
