I pushed two new branches (connect and test) to my Bitbucket repo. After some time, they got listed in Plan Configuration > Repositories

But it's not avaliable in Plan Configuration > Branches where I want to create a plan branch

Even not when I search for e.g. test

So I tried to create it manually. This allow us to create the plan branch, not linking it to the corresponding Bitbucket branch:

I also tried to add the Repo in Plan Configuration > Repositories twice (one entry with master branch, the other test branch). But it's not possible to select the desired branch. The link between Bamboo and Bitbucket itself work on the master branch, only other branches make issues here.
