FFS Conveyor Decision point as station....issue with bahavior

I am using Decision point on conveyor as station and all cycle times given as Generic activity to Decision points. Issues coming as below : 1) Requirement is Part should not leave the station 01 (decision point) till the time next station 02 finishes the operation and available to take preceding part from station 01......in my model decision point is releasing the part immediately after finishing its cycle time and not considering that nest station is busy......How to do this?

2) I have given Normal Distribution time to each station but still its considering constant cycle time only after the Run (from report)....so do i need to change any other settings to consider distribution cycle time?
