Can't toggle comment after format Go source about nvim-comment HOT 1 CLOSED

'm trying to replicate this but struggling.
I've got a simple main.go:

package main

import "fmt"

func goats() {
	fmt.Println("this is some text")
	fmt.Println("what of it")

	fmt.Println("this is some text")
	fmt.Println("what of it")

	fmt.Println("this is some text")
	fmt.Println("what of it")
}

func main() {
	fmt.Println("hello mate")
	goats()
}

Commenting out line 9+10 with gcip, indenting line 17 too far to the right and then running gofmt: :!gofmt -w %
I'm able to use motions to uncomment out lines 9+10 again as expected.

Are you able to give me some means to replicate this?
