StateTree - the state transitions to the next one even though the task did not call `FinishTask`.

Hi.
I use UE 5.5.4
Task STT_Print_String don’t call FinishTask

Can someone explain to me why, in the examples below, the State transitions to the next State even though STT_PrintString does not call FinishTask? I would expect the task and the State to “pause” or remain active if FinishTask is not called.
