it DOES NOT Matter how many lv.2's you use as the only ones you can effect are the LV.3's so for example in your case you only got 1 Weapon lv.3 ,  So your first Weapon lv.3 will be the same as the first Weapon Lv.2., If not it would mean that you did not purify the correct amount of Weapon lv.2's, You only got 1 Weapon lv.3 so just purify only 1 Weapon lv.2 and the Weapon lv.3.
