Describe the bug

I tried to play with a blue magican set bonuses(Arcanic conversation IV, x3,5magic damage, Extend potion duration) and mention that it's starts deal 3.5x magic damage only on second hit to the target, first hit deal usual damage without magic multiplayer. So after mention it in usual survival world, i've tested it in a creative world on different creatures and with different swords with diff enchantments on it and without any enchanments, and get the same result magic focus and blue magican x3.5 magic damage start working only at 2nd hit, however arcanic conversation works normally.
P.S (A myth no more set bonuses with it (arcanic conversation III+magic focus II) have the same problem, magic focus here start working only on second hit to mob.
