Advanced Conveyor Control using PF

I make a training model in Advanced Conveyor model using PF.

The phase 2 model shows some issues in the case of buffer conveyors when reversed.

Only one time of the first buffer lane and others show some times reversed.

The conveyor shows 'reverseed' state but the item can't move reversed.

What's the problem of it?

Depending on the floating point math the DPs on the buffer lanes might trigger again when the direction is reversed so the item is stopped again. You can circumvent this by having the trigger based on the leading edge of the item.
