When I first go to an island, all of the monsters have the coin alert up, but after a couple of seconds they all go out except for one monster of each type. I think it's the "oldest" monster of each type that generates coins -- that is, the one that has been on the island longer than any other monster of its type. If I sell one of those, another one takes over the task of generating coins.

It's odd that none of the monsters on your Space Island are generating. I assume that it's not just because you've collected recently, and you have to wait until the "oldest" monster of each kind has coins to collect?
