Decision Point distance for sending flowitem

HI !
We are trying to do a simple conveyor logic but in a tiny space. According to where we place the decision points, the redirection of the flowitems are done correctly or not.

The problem for one point is that we have little space for the decision point and it does not work when we place it there. On the attached image, i have circled in red the place the decision point should be and where it does not work to redirect the flowitems on the path drawn by the black arrows. In green is the place, where the decision point is to make the logic work. But we can't place it there.

The decision points are firing with the leading edge.

Are we missing something here ?

Update:

I think once the item leading edge is past the side transfer, it cannot be redirected. But this seems strange. The trigger on the decision point is working, but the redirection is not.

Hello @Sebastien,

from your screenshot it looks like the leading edge of the item might already be past the center of the decision point when it enters from the lower conveyor (based on the size of the default box). Thus, the logic of the decision would never trigger.

Maybe try switching it to trigger with the item center.
