    Hi!
    I have a lot of problems with OP… but this one is the most annoying.
    In column "duration" is shown 0 days, but there are subtasks below where everything with time is ok.

    2 hours Formal acceptance 0 days  (<--why?!)
    2 hours Report to stakeholders 0.25 days

    I would really appreciate any help.
