Does not work (or I don't understand how to use it)

I have the following config:

// Corefile
spiral.sh {
	file zones/spiral.sh
	alias
}

; zone
http-pool.spiral.sh. 3000 IN A 128.116.205.8
http-pool.spiral.sh. 3000 IN A 45.61.184.138
spiral.sh. 3000 IN CNAME http-pool.spiral.sh.

dig output:

;; ANSWER SECTION:
spiral.sh.		3000	IN	CNAME	http-pool.spiral.sh.
http-pool.spiral.sh.	3000	IN	A	128.116.205.8
http-pool.spiral.sh.	3000	IN	A	45.61.184.138

What am I doing wrong? I would like to show just the A records and not the CNAME, as shown in the example on the README.

Additionally, include this block (or equivalent) in your Corefile:

# This is used to resolve CNAME records by the `file` plugin. Modify accordingly
. {
	forward . 1.1.1.1 1.0.0.1
}

If you already have included it, then it is likely a bug with this plugin. I'll check it out soon.
