Reversing conveyors causes entry points to move

Im having issues with trying to reverse a conveyor to get rid of a internal pallet after the one way pallet has been picked up. Attached is a simplified version. Reversable conveyors.fsm

The issue seems to be that setting the speed to a negative value causes the entry and exit points to be mirrored. First picture is the actual configuration.

Second picture is after reversing showing the next pallet sandwich entering. Its not immidiatly clear that the transfers has moved, but if you pause and click on one of them it jumps to the position as shown below.

Since they are moving (and not moving back when reversing the speed back to normal for the next pallet sandwich) the next item cannot find its way and just ejects the conveyor in the end

Hello @Guldberg,

This issue is occurring because the item is entering the conveyor as it is accelerating. This is a bug and the development team has been notified. As a work around you can set the acceleration/deceleration for the conveyor to 0.
