Git flow setup script minor bug

[ghost]

A setup script nem teljesen kerek:

$ scripts/git-flow-setup.sh
Enter passphrase for key '/c/Users/inf3rno/.ssh/github':
fatal: A branch named 'develop' already exists.
Using default branch names.

Which branch should be used for bringing forth production releases?
   - develop
   - master
Branch name for production releases: [master]

Which branch should be used for integration of the "next release"?
   - develop
Branch name for "next release" development: [develop]

How to name your supporting branch prefixes?
Feature branches? [feature/]
Bugfix branches? [bugfix/]
Release branches? [release/]
Hotfix branches? [hotfix/]
Support branches? [support/]
Version tag prefix? []
Hooks and filters directory? [E:/creation/software developer/projects/webproghu_                                                                                                                                  dev/.git/hooks]

git flow config after setup:

Branch name for production releases: master
Branch name for "next release" development: develop
Feature branch prefix: i-
Bugfix branch prefix: i-
Release branch prefix: r-
Hotfix branch prefix: h-
Support branch prefix: s-
Version tag prefix:

Igazából a "fatal: A branch named 'develop' already exists." rész, ami zavaró benne, de ránézésre mintha minden lefutna. Ránézne valamelyikőtök, hogy ez befolyásol e bármit, vagy maradhat így?

Egyébként a develop branch-re voltam checkout-olva, amikor indítottam. A master branch-en nincs ott a script.
