NPC quests Bug

[Hekaro]

i was doing a farming quest in tynen before a while ago which it was killing 20 cows. i killed 20 cows already but the counter didnt appear and when i returned back the NPC still asking me for them. i have done this quest many times but i think its bugged now or my char is bugged. the NPC name is Vandegal cord 351 229 in tynen.
and today Aran the NPC that gives the daily job 359 311 which is located in tynen, i find out that if i get a killing quest and get another killing quest then the first one will be disabled.. could you fix that or at least reset my quests so i wont get 2 killing quests same time at all.
Char name DragonFire

thank you
