Let me guess, this is one of the "I-take-vanilla-Minecraft-and-mess-around-with-third-party-tools-now-my-minecraft-is-broken"-issues ?
Nevertheless, other mods gave the hint to the better description in MC-4236
when you hover your mouse over the firework, what does it say besides: "firework rocket"?
