Date field coming as General value in qlik

[Anonymous]

I have a Dates of each month in the column

When i am loading the date it is coming as a general value.

I tried changing the excel format to date. Still it is coming as a general value.

Please see the date image of the excel and QLik sense

May be this

Sum({1<Billing_Date={">=$(=Date(YearStart(Max(Billing_Date),-2)))<$(=Date(MonthStart(AddYears(Max(Billing_Date), -2), 1)))"}, Year1={"2016"}>} value)
