How do i use 'Update Copyright...'

Hello everyone,

i'm trying to understand how to use the 'Update Copyright...' feature.

In my source files i have a header like this:

# This file is part of MyApp.
# Copyright © 2000-2018 MyApp Project
# 
# MyApp is free software: you can redistribute it and/or modify it under
# the terms of the GNU General Public License as published by the Free

# with MyApp. If not, see <http://www.gnu.org/licenses/>.

In Settings > Editor > Copyright > Copyright Profiles i have added the above text and replaced 2018 with $today.year .

The regexp i set to Copyright © 2000-\d{4} MyApp and allow replacing string to Copyright © 2000-20[0-9][0-9] MyApp.

Now when using 'Update Copyright...' the first two lines will be replaced with the full copyright text. That means the text blocks 2-4 are now doubled.
