PDM TASK WORKS ONLY AFTER CHECK IN

Good afternoon ,having an isue with PDM task. For a start i want to change a sheet format in a transition. This is ok you create TASK, right click button it works, however if its integrated into workflow it sets all my variables, then check in, then starts a task to change sheet format - and then nothing happens.
