ALM Octane branch collector failure for Duplicate keys.

In our octane instance somehow we have 2 branches in octane with the same names (different id). Most likely the developer might have created a branch , deleted the branch and then recreated a branch with the same name. The branch collection should not fail but continue to process remaining branches and just skip the problematic branch.
