Report Templates; AccountHistoryList Reports do not give a warning re "DisplayColumns" parameter on Layout page

A Report Template based upon the AccountHistoryList Report does not give a warning re "DisplayColumns" parameter on Layout page, like "IncludeColumns" in other Reports.

The warning is "WARNING: A Parameter named 'DisplayColumns' exists which has a value and may cause one or more columns not included in this layout to be made visible when the report is run. It is recommended that you clear the value from this Parameter and make it invisible unless you want Users to have the option to vary the layout.".

It would be typical that the DisplayColumns parameter is removed so that the User cannot override the layout/ columns defined on the Report Template.
