The disambiguations have been fixed to be clearer and the wandering tags are back under their proper fandom. We hope that helps, and thank you for letting us know about the issue!
However, we won't merge the two nominated fandoms at this time. This is because the two different tags technically refer to different things: one refers to the single game "Trails of Cold Steel," and the other refers to the four different games that make up the Trails of Cold Steel series. While this might be a mistake, we'd like to err on the side of caution, as it is not uncommon for nominators to want to distinguish between a single installment of the series and the series as a whole. Thank you for understanding, and let us know if you come across other issues!
