Old World cards question

By maamets, in Chaos in the Old World

Hi,

What happens to the old world card that is being in the second slot but the first one is empty at the end phase? Will the OWC be removed from the game or it will be removed only when a new card actually takes it's place?

If two OWC's are present on the table (as usual) then in the End Phase both cards normal text is executed or only the card in the first slot?

The card stays until "bumped". Rules, page 10.

Slot 1 is resolved first. Rules, page 20.
