Pit Of Undying - "Bonus" Boss Doesn't Give x30 Seal of the Undying

Bug Name:

Pit Of Undying - "Bonus" Boss Doesn't Give x30 Seal of the Undying​

Bug Description:

The Musa ''Bonus'' Boss gives guaranteed x30 Seals when you kill him as a bonus round boss, like you see here for Kauha / Kordun.
Yulho (Musa)
''He has a lower chance of appearing but gives Seals of the Undying x30 when defeated. He is a samurai and is fairly easy to kill with no special strategy.''
Kordun "bonus" boss doesnt give anything, killing him does nothing except waste time.
I dont think this is intended, is he suppose to give nothing?

EDIT: The state of the bonus boss Kauha / Kardun is the same as retail as it currently is on Gamez, which means that they do not give x30 Seals on death, the bonus round bosses except Yulho don't give seals on retail as well - an oversight of Pearl Abyss.

Would it be ok to ask if it's possible to add same reward from Yulho for Kardun NPC when appearing as a Bonus Boss round?

TRI Insignia Pit of Undying, Between stage 2-3​

How to reproduce/proof:

​

 

Well, in fact, this bug should be that when the second battle is over and the third is continued, incorrect bonus boss will appear. This bug is not limited to any level.
Probably because of this.
Duel of the Undying is not only Yulho in bodcodex, there are also many versions, but they are not even application in retail and no reward set, normal should not appear.
bonus boss only Yulho, everything else is abnormal.
This bug has actually existed for a while, at least I remember it has been there since update 3205.
It's just that I didn't go to Pit Of Undying much later, until this maintenance fixes Van Riker.

I tested duo in the morning. Yulho will still appear. After defeating Yulho, Kunga appears, but the target of the third battle is Bennet.

 

Hi,
The state of the bonus boss Kauha / Kardun is the same as retail as it currently is on Gamez, which means that they do not give x30 Seals on death, the bonus round bosses except Yulho don't give seals on retail as well - an oversight of Pearl Abyss.
A Friend on EU Retail tested this and he also didnt get seals from Kauha / Kardun during DUO and TRI Pit of Undying.
