You have an Editable List View with only a Delete toolbar button and the "Execute the Delete method" rule is configured on the Delete Toolbar Button is clicked rule.
Resolution
It is expected behavior on K2 5.5 that the list view does not refresh automatically when using the 'Execute the Delete method' rule as this is not the default approach. There has been a lot of improvements and streamlining of the List View rule events/actions between K2 4.7 and 5.5.
