Unable to pay retreat cost with Fezandipiti

I have tried it in a few separate games now, to make sure it wasn't a one time thing. When I retreat Fezandipiti from the active, it goes to the normal action screen to select the energy, only it you can't pick any of them. I've tried going pack, searching the discard pile, and then back to the cost screen, but still nothing. I have to wait for the timer to run out and the game to select the energy. Which wouldn't be a huge problem except when I'm trying to get a specific energy into the discard pile.
