In Dragonball GT, why were there only 7 shadow dragons if there was definitely more than 7 wishes made?

Question

And syn shenron wasnt even born form a wish, which only leaves 6 dragons made from wishes. Haze was born from bringing back Upa's father Bora, Rage was born from wishing goku back to life, nuova was born from king piccolos wish for youth, oceanus was born from oolong's accidental wish for panties *lol*, Eis was born from reviving all the people killed by king piccolo, and naturon was born from the wish bringing back all the people killed by majin vegeta.

That still leaves out the wish to restore the forest in Coolers revenge, garlic juniors wish for immortality, the wish to bring back trunks, the wish to take out the bomb from android 18's body, and im sure theres more that im too lazy to remember. so if somsone could shed a little light that would be great because this is really bugging me lol

Answer 1

Yea noticed that too it is bugging but maybe they wanted to appear only the dragons from the most important wishes ... dunno for sure ;)  

Sry but i dunno but its freakin me out to ...  

Answer 2

They(writers and creators) made the dragons appear from the most memorable wishes and also they want the number of dragons to represent the number of balls so they could have the dragons separate like the dragon balls after wishes. Don't u reckon Syn Shenron looked weird? He was so weird. well i didn't like him. He looked worse on the game.
