Im having trouble the get aligned data with dates for some instruments

Im having trouble with the API. As you can see below, the resultant dataframe comes with null values on the last dates, and values on the first dates. The problem is that the "MATD3.SA" didnt exist before 2021.
On excel, with same parameters, the dataframe comes alright, with null values up to 2014. So why is this happening on here?

dic_parametros_fundamentals_Q = {

            'SDate': -140,

            'Period': 'FQ0',

            'EDate': 0,

            'Frq': 'M'
        }


df_chunk = fundamental_and_reference.Definition(

                universe='MATD3.SA',

                fields=['TR.CompanyMarketCap.calcdate', 'TR.F.TotRevenue.fperiod',

 'TR.F.TotRevenue.fperiod'],

                parameters=dic_parametros_fundamentals_Q 
            ).get_data().data.df

            print(display(df_chunk))

display(df_chunk ):
