[NAPA]

There are duplicate inserter guidelines.

Not a bug

First set of guidelines is because of train station and they show how train will align after arrival. Second is box over cargo wagon to confirm that inserter connects with this entity. Same happens when building inserter in between belt and assembler where both with be marked.
If you build fluid wagon it will not show this second box because inserter cannot interact with fluid wagon.

sorry, It is not a bug.
