Nah, it does that on purpose. The levels of getting the trophies are denoted by the stars next to it. So once you get 5 CE fighters, it will say unveil and you will have completed a level of that trophy and advance to the next level, where you will then have to get a few more of those fighters to unlock the next level. It will keep happening like that until you've reached all 5 levels off all trophies.

The reason I think this is is because EA wants you to invest gold in the game when buying those NP, IC, CE/NCE, IE fighters and whatnot. Also, it gives players something to do as far as the game is concerned. As far as the progress having been reset for that Rank 1 trophy goes, I messaged them about it multiple times and have gotten replies that it may be a bug on their part and that an update may fix it or something. Not really much of an answer from them I know, but meh.
