Extra comma on Holidays overlay when using NextJS

[dolaumzim]

Hello everyone!

I'm trying to use the datepicker and so far everything is going according to the plan, except for a small thing:

The holidays overlay text is outputting an extra comma.

Here is the code so far:

  const holidaysObj = [
    { date: '2024/01/30', holidayName: 'Fim de Mês' },
    { date: '2024/01/30', holidayName: 'Fim de Mês 2' },
    { date: '2024/01/31', holidayName: 'Emenda Fim do Mês' },
    { date: '2024/02/12', holidayName: 'Dia Dos Namorados' },
    { date: '2024/04/13', holidayName: 'Páscoa' },
    { date: '2024/05/01', holidayName: 'Dia do Trabalho' },
    { date: '2024/06/15', holidayName: 'Corpus Christi' },
    { date: '2024/06/16', holidayName: 'Emenda Corpus Christi' },
  ]

<DatePicker
        className="rounded-sm border-[1px] border-gray-950 text-center"
        filterDate={isWeekday}
        showPopperArrow={false}
        selected={boolStartDate ? startDate : null}
        onChange={(date: Date) => handleChange(date)}
        formatWeekDay={(nameOfDay: any) => nameOfDay.slice(0, 1)}
        excludeDates={excludeDays}
        holidays={holidaysObj}
        maxDate={new Date('2024/07/15')}
        placeholderText="mm/dd/yy"
        dateFormat="MM/dd/yy"
      />

And here is the result I'm having:

I tried running the code on different PCs and got the same result. The only time I got a different result was when I used Vite to create the project, instead of NextJS, and with Vite it works perfectly, so I am wondering if there is any incompatibility with NextJS for this case.

I tried searching for other discussions about this subject but found nothing, if anyone could help me I'd be very grateful!
Thanks in advance!
