Never really paid attention to those images but based on the cstoys review I saw there was an image of the ranger that you could see once it lit up, so maybe that's what you were seeing before.
Some more quick notes
Looks like the toned tone the cooking phrases for Spada at least for this episode, so I'm cool with that. Somebody still needs to start punching Lucky in the balls every time he says "Lucky" though.
I like the idea behind the idea of Balance and Naga, where the robot is tying to help the organic to learn emotions. It's a unique twist in the standard trope. Although I do wonder if Balance's shall we say thieving nature is going to come into conflict with the others at some point.
And apparently you don't need to search for Voyagers, you can just summon them out of thin air once you become a ranger.
