Issue with unformat gui slot

[Fusezion]

Description

So while using Skript-GUI I tend to use (integers from 0 to 53) and loop x times
this allows me to do large changes with a smaller amount of code and looks neater
however, I've noticed that whenever I use unformat gui slot (integers from 10 to 16) or loop {_value} times:
it only ever loops once and then seems to cut off anything else in the gui creation

Steps to Reproduce

simply add this code into a test server and run the /example command if it's anything like mine it
should open the GUI and have all GUI slots filled with black glass pane with only slot 0 being air

command /example:
	trigger:
		create a gui with virtual chest inventory with 3 rows named "":
			format gui slot (integers from 0 to 26) with black glass pane named " "
			loop 9 times:
				unformat gui slot (loop-value)-1
			unformat gui slot (integers from 9 to 17) # nothing changes when I use `slots`
			unformat gui slot 18,19,20,21,22,23,24,25 and 26
			format next gui slot with stone
		open last gui to player

Expected Behavior

I'd expect to see a gui slots air besides slot 0 being stone

Errors / Screenshots

this image here is an old screenshot prior to me changing the skript originally it only unformated slots (10 to 16)
however, while I was testing I noticed it did the same with unformat gui slot 10, 11, 12, ect

Server Information

• Server version/platform: Java, Paper Latest (1.16.5)
• skript-gui version: Skript-Gui, 1.2.2
• Skript version: Skript, 2.5.3

Additional Context

I've never had this issue in the past when using TuSKe so I do believe it's a bug

I will take a look into this issue when I next get the chance :) (should be pretty soon)

I couldn't exactly replicate your issue using the alpha nightly builds, but I did notice it wasn't exactly working as expected. With the latest commit above merged, I believe this issue has been fixed. Here's what it looks like now:
