Could not remove jobs properly

[vigneshr6]

I have the below code

package main

import (
	"fmt"
	"time"

	"github.com/jasonlvhit/gocron"
)

func main() {
	funmap := make(map[string]func())
	for i := 1; i < 6; i++ {
		funmap[fmt.Sprintf("func%d", i)] = getJob(i)
	}
	gs := gocron.NewScheduler()
	gs.Every(5).Seconds().Do(funmap["func1"])
	gs.Every(5).Seconds().Do(funmap["func2"])
	gs.Every(5).Seconds().Do(funmap["func3"])
	gs.Every(5).Seconds().Do(funmap["func4"])
	gs.Every(5).Seconds().Do(funmap["func5"])
	fmt.Println(gs.Len())
	gs.Start()
	time.Sleep(time.Second * 10)
	fmt.Println("*************************")
	gs.Remove(funmap["func3"])
	gs.Remove(funmap["func5"])
	time.Sleep(time.Second * 10)
	gs.Clear()
}
func getJob(i int) func() {
	return func() {
		fmt.Println("This is func:", i)
	}
}

I want to remove jobs with their names.but It deletes first two entries.
How to solve this?
