Rebex Zip: ActionOnExistingFiles.OverwriteAll does not work

Hi there,

I´m using/trying out Rebex Zip version 7.0.8657.0 (Rebex ZIP for .NET Framework 4.6-4.8) and found an issue when extracting files.
That´s what I do:

_archive = new ZipArchive(zipFileFullName, ArchiveOpenMode.Open, ArchiveAccessMode.ReadWrite);
FileSet dataToExtract = new FileSet(RootPath, "*");
ArchiveOperationResult result = await _archive.ExtractAsync(dataToExtract, extractPath, TransferMethod.Copy, ActionOnExistingFiles.OverwriteAll);

When a file already exists on the destination the event ProblemDetected fires with ProblemType = FileExists

What is wrong with that. Do I miss something?

Best regards
Matthias
