AT:

• given:
  • I save a report with a given order of when filters where inserted (e.g. first date filter f1, variable filter, f2 another date filter f3)
• when:
  • I retreive the report
• then:
  • I can infer the insertion order or the insertion order is preserved (e.g. first date filter f1, variable filter f2 and another date filter f3)

Hint:
Have a look at the new filter datastructure:
