Storage Routes and Replacement

Ahoi Captain´s,
i found a strange behavior. I build a row of storages. Some for delivery and some for pick up with export routes.
Then i had to rearrange them, in that case just flip the row of storages.
So i copied them and replaced them with "shift + left click".
Now the assigned routes were transmitted to the wrong storage.
Hard to tell, so i made a video and attached it.
