How Do I Remove The Double Arrow?

Hi, I added a script template which is a Limelight Female Avatar thing for the first chapter and how do I remove the double arrow thing because I change my mind and I don’t want the template anymore, P.S, My platform is iOS.

The Double Arrow Thing

Can’t you just backspace?
Select the line below it and just click delete until it gets rid of it. It should get rid of it, it worked on mine.

Select the line below it

And just hit delete

Since it’s composed text:
#composed lines{
lines you wanna hide go here

You can just delete the {}

Okay, thank you!
