#Error when a new column added in a Calendar

Hi,

I create a Calendar using a below code:

dcalendar3 =

            ADDCOLUMNS(

                CALENDARAUTO();

                "Ano";FORMAT([Date];"YYYY");

                "Mês";FORMAT([Date];"MMMM");

                "Mês Curto";FORMAT([Date];"MMM");

                "Núm Mês";MONTH([Date]);

                "Trimestre";FORMAT([Date];"q");

                "Mês/Ano";FORMAT(([Date]);"mmm") & "/" & YEAR([Date]);

                "Ano Mês"; CONCATENATE(YEAR([Date]);FORMAT(MONTH([Date]);"00"));

                "Dia da Semana";FORMAT([Date];"ddd");

                "Núm Dia Semana";WEEKDAY([Date]);

                "Dia Útil"; SWITCH(WEEKDAY([Date]);7;0;1;0;1);

                "Feriado";LOOKUPVALUE(Feriados[Feriado];Feriados[Data];[Date];"")

            )

I need to add a column to check if it's a business day or a holiday. And I'm using the following code for this:

Dias úteis sem Feriados = if(AND(dcalendar3[Dia Útil]=1;dcalendar3[Feriado]="");"Dia útil";"Dia não útil")

Sometimes when I add a new column, it causes an error in all the data in the column. It has already happened, for example, when I refer to one of the columns in the calendar, as is the case now. This time I had no mistakes, but they often haunt me.

Thanks!
