New branches on new repositories not showing in "Git instructions"

I create a new project on http://git-dev.drupal.org

On my PC the commands are:

mkdir fransk-test2
cd fransk-test2
git init
echo "name = fransk-test2" > fransk-test2.info
git add fransk-test2.info
git commit -m "Initial commit."
git remote add origin ssh://franskuipers@git-dev.drupal.org:2222/project/fransk-test2.git
git push origin master
cd ..
rm -rf fransk-test2/
git clone ssh://franskuipers@git-dev.drupal.org:2222/project/fransk-test2.git
cd fransk-test2
git co -b 7.x-1.x
ls -l
touch README.txt
git add .
git commit -m "Added: README.txt"
git push origin 7.x-1.x

Went back to http://git-dev.drupal.org/project/fransk-test2/git-instructions

I expect a select-box with 2 branches: master & 7.x-1.x but only the master branch is showing.
