Please, does anyone know how to set up: Guild Rush: Elite Boss

We've already tried setting both Lv1 and Lv3 and Lv5 but failed to get the titles :(

If the inability to get the titles mentioned is a bug in the BDM game and the BDM team (Pearl Abyss) can't fix it, it would be wise to inform about it ! ...dear admins and programmers. Thanks. JAACO

Combat Titles:

A Blessing to All

Guild Rush, Defeat Orgoh

Even Orgoh the Greedy is nothing when I'm with my guild members.

The Prideful One

Guild Rush, Defeat the Dim Tree Spirit

Defeating Tree Spirits feels like a picnic now.

Perfect Teamwork

Guild Rush, Defeat Cadry Gatekeeper

We defeated Cadry Gatekeepe. Together we make the team!
