Data List in wrong order

[gcclinux]

Test: `package main

import ( "fmt" "strconv" "time"

"github.com/deroproject/graviton"

)

func main() {

store, _ := graviton.NewDiskStore("db/graviton.db")
//memdb, _ := graviton.NewMemStore() // temporary memory db
ss, _ := store.LoadSnapshot(0)
tree, _ := ss.GetTree("root")

// Create a list of date and store in database
fmt.Println()
today := time.Now()
keys := 1
for x := 0; x < 10; x++ {
	date := today.AddDate(0, 0, x)
	save := fmt.Sprintf("%02d-%02d-%04d", date.Day(), date.Month(), date.Year())
	tree.Put([]byte(strconv.Itoa(keys)), []byte(save))
	keys++
}
graviton.Commit(tree)

fmt.Println()
// Get individual value based on key = "1" example
var key string = "1"
value, _ := tree.Get([]byte(key))
fmt.Printf("SINGLE: key=%s, value=%s\n", key, string(value))
fmt.Println()

// Get first value stored in database
first := tree.Cursor()
k, v, _ := first.First()
fmt.Printf("FIRST: key=%s, value=%s\n", k, v)
fmt.Println()

// Get last value stored in database
last := tree.Cursor()
for k, v, err := last.Last(); err == nil; k, v, err = last.Next() {
	fmt.Printf("LAST key=%s, value=%s\n", k, v)
}
fmt.Println()

// Get last 5 values stored in database
five := tree.Cursor()
count := 5
for k, v, err := five.Last(); err == nil && count != 0; k, v, err = five.Prev() {
	fmt.Printf("LAST%s key=%s, value=%s\n", k, k, v)
	count--
}
fmt.Println()

// Get all values stored in database
c := tree.Cursor()
fmt.Println("ALL:")
for k, v, err := c.First(); err == nil; k, v, err = c.Next() {
	fmt.Printf("key=%s, value=%s\n", k, v)
}

fmt.Println()

} `

The out put of ALL values + LAST 5 is incorrect Example:

LAST10 key=10, value=30-01-2023
LAST7 key=7, value=27-01-2023
LAST2 key=2, value=22-01-2023
LAST8 key=8, value=28-01-2023
LAST9 key=9, value=29-01-2023

ALL:
key=1, value=21-01-2023
key=3, value=23-01-2023
key=5, value=25-01-2023
key=6, value=26-01-2023
key=4, value=24-01-2023
key=9, value=29-01-2023
key=8, value=28-01-2023
key=2, value=22-01-2023
key=7, value=27-01-2023
key=10, value=30-01-2023

Please advise how I can correct this as ORDER is very important for me.
