Exception on loading xlsx having multiple _xlnm.Print_Area

[kenjiuno]

Sometimes LibreOffice Calc (version 6.2.0.3 Windows I have tested) seems to produce xlsx file that EPPlus cannot read.

multiple_print_areas.xlsx

Program.cs

using OfficeOpenXml;
using System;
using System.Collections.Generic;
using System.Globalization;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace ConsoleApp28
{
    class Program
    {
        static void Main(string[] args)
        {
            Thread.CurrentThread.CurrentUICulture = CultureInfo.InvariantCulture;

            var fileInfo = new FileInfo(@"C:\A\multiple_print_areas.xlsx");
            var package = new ExcelPackage(fileInfo);
            var workbook = package.Workbook;
            var worksheets = workbook.Worksheets;
            var worksheet = worksheets.First();
        }
    }
}

The duplicated _xlnm.Print_Area is generated when I used:

Format > Print Ranges > Add Print Range

in LibreOffice Calc.
