No "add another item" button.

Hi,
I found Gmaps much better than GMAP+Locatin for me.
When i add a multiple values files to a node with count "no limit", i get on the node/edit form 2 maps, but there is no "add another idem" button, so i can`t add more than 2 locations.
I tryed this multiple field on different themes, and everywere i haven`t seen "add another item" button.
