Bug with twilight robe set

i have a problem with twilight set, i bought all the pieces except the twilight gloves, i've put the magic type robe set at the blacksmith and the set appears to be complete. but i have 1000 less m.atk and 100 less casting speed with twilight than with immortal when i'm full buffed and with party solidarity lvl 3, why's that, it's because i don't have the gloves or there's a bug?? because the twilight set applies all the effects with 4 pieces and i have them. i should have more m.atk because twilight set gives you +2 int and 184 m.atk more and immortal set only gives you +1 int . and i should have the same casting speed with twilight and with immortal set and i have 100 less cast speed with twilight. if it's because i don't have the gloves it shouldn't be because the twilight gives you the same effects with 4 pieces than immortal with 5 pieces, except the 0,6 mp regeneretion of the immortal set and the +2 int and 184 m.atk of the twilight (it's for this effect that i should have more m.atk with twilight) and the cast speed should be the same. in coclusion the bug is that i don't get the 15% m.atk additional and the 12% casting speed additional, like i asked, it's because i don't have the gloves??, if it's because that it should't be.

twilight set:-2 parts: int + 2, men -1, casting spd. + 3%
-3 parts: mp + 202, resistance to sleep + 7
-4 parts: m. atk. + 184; magic critical + 3%; resistance to attributes + 10, casting spd. additional + 12%, m. atk.
additional + 15%

immortal set: -2 parts: int + 1, casting spd. + 3%
-3 parts: mp + 185; resistance to sleep + 5
-4 parts: mp regeneration + 0.6
-5 parts: magic critical + 3%; resistance to attributes + 10, casting spd. additional + 12%, m. atk. additional + 15%

 

ok problem solved, it was because i did't have the gloves :s
