Raptor landing deck not cleared for landing fighters

[Xkuka]

<-- Blue circles fighters in docking queue, red circle the only landing deck that makes room for landing fighters. Result = it takes awhile...

Is this a known issue? Can someone with vanilla reproduce this?

Side question: Why is my image not shown properly? Tried all the bb codes suggested here and different variants of the image link.

Edit, this seems to happen when adding new fighters to the Raptor and the deck already occupied. But is no problem when all fighters land.
