For "Spd Def Bond 1", "Spd Def Bond 2", and "Spd Def Bond 3" when you mouse over the icon the help text reads "Grants Spd/Def+3 to this unit during combat if unit is adjacent to an ally." for each one. Rather than +3, +4, and +5 respectively.
Just in case I tested it with multiple heroes and other bond skills. All Spd Def bond skills had this issue on every character I tried it on. All other bond skills displayed the correct text.
