Yeah, I wasn't quite convinced of it either. I did go to the power plant directly after Lostelle and it was just the major event I remembered that could've checked something, sorry about that. But from your new picture the "Defeated electrode (2)" flag does match up to the seafoam islands current because it was checked after I saved next to Articuno and moved all boulders to their locations. I did some more walking around in the power plant and noticed that the "Defeated electrode (1)" was checked after battling the Electrode at the bottom next to the machine.
