 label.branching.general.instructions = Place the lesson participants in their branches. Initially you can add and remove learners, but once a participant starts one of the branches then you will not be able to remove learners from any branches. If you try to remove someone from a branch and they will not remove then check their progress - if they start using the branch while you are on this screen you will not get any errors but you will not be able to remove them from the branch. You will still be able to add learners to branches.
