Grand Chase Resistance 3rd Job help

[fukudots.com]

Hello.
Selenium here.

And I would like to report this kind of Quest which is the Arch Ranger Mission.
I have already the Requirements which is the Ruby, Pocket knives, and the Sword. and I have 10 medals. But the Mission requires me to have 50 Medals.
But after I acquired 10 Medals, I can't acquire any medals anymore which is very annoying. and Every win, there's no Medals. so I would also love to have a quick response on this one. Is this a bug? Or the creator has any issues with Lire here?

Thanks for Replying. I hope the Creators of GCR will read this.

Delete the current mission, rebuy one from the shop, and re-activate it. You still should have your items so you can still complete the mission.
