I’ve got the Forever Friends active on my account and when selecting tags for a pokemon, the first custom tag has a line of text under it that reads “Visible to Forever Friends”. Maybe it is intended to be a Remote trading specific tag that’s going to be forced in that spot but right now whatever tag you move to the top gets that extra wording. (3rd screenshot is from a another account that previously had no tags configured but also has the Forever Friends active)
