when item moves in-line transfer conveyor ...

I found item ridiculous moving near in-line transfer point to straight.
The item move curved and stop at in-line transfer point not moving straight like attached screen.

What's wrong with it?

Help me.

I found what's the problem.
If the exit route does not exit, the item moves ridiculously.

The sink or other objects should be connected to the last conveyor.

Thanks.
