Can not copy the sheet when the sheet has button.

[GuangZhouDekang]

If the sheet has button. can not use copy a new sheet.

It will raise An unhandled exception of type "System.InvalidOperationException" occurred in EPPlus.dll.
The Inner Exception is: Cannot access a closed Stream.

Here is my code.

private void button1_Click(object sender, EventArgs e)
{
FileInfo templateFile = new FileInfo("Original-With-Button.xlsx");
FileInfo newFile = new FileInfo("Copy-With-Button.xlsx");
using (var package = new ExcelPackage(newFile, templateFile))
{
package.Workbook.Worksheets.Copy("Sheet1", "Sheet2");
package.Save();
}
}

If I remove the button in Sheet1, the copy it work right.
How can I copy the sheet with button?
