Incorrect decompression

[venffet]

hello, I found an example of incorrect decompression.

cat rardecode_test.go

package rardecode

import (
    "fmt"
    "io"
    "os"
    "testing"
)

func TestDecode(t *testing.T) {
    ar, err := OpenReader("A62PC版+手机版.rar", "51mh")
    if err != nil {
        t.Fatalf("failed to open reader: %s", err)
    }  

    for i := 0; i < 15; i++ {
        af, err := ar.Next()
        if err != nil {
            t.Fatalf("failed to advance the next file: %s", err)
        }  
        filePath := fmt.Sprintf("tmp/%d", i) 
        fw, err := os.OpenFile(filePath, os.O_CREATE|os.O_RDWR|os.O_TRUNC, 0644)
        if err != nil {
            t.Fatalf("failed to open file: %s", err)
        }  
        io.CopyN(fw, ar, af.UnPackedSize)
        fw.Close()
        t.Logf("index: %d, name: %s, filesize: %d", i, af.Name, af.UnPackedSize)
    }  
}

go test -v

the rar file: A62PC版+手机版.rar download link:
https://drive.google.com/file/d/1yEd3cUGKDw-nyDo64kmv9GDe8ljsmLLI/view?usp=sharing

the filesize of 10th file is expected to be 84381696 but actual size is 46071812，what‘s the problem?
