Bug "bounty n (Normale)" instead of the name of a boss

Since the 2 last patches, in Mercenaries (French version) : the visitor tasks don’t display the name of the boss of a bounty anymore, instead of the name of a boss for a bounty, it is written : “bounty n (Normale)”
(FR client on PC)
So, it is impossible to know which boss I should fight for completing the task and I don’t have the time to try them all. 3 or 4 other French people reported the same bug in other posts, one of the French forum which will never be seen by developers (here : https://eu.forums.blizzard.com/fr/hearthstone/t/description-des-primes-des-mercenaires-en-visite-au-feu-de-camp-buggée/5763) and the other one in another post on this forum, here : 25.0 Known issues - #23 by Autum-11999

Blizzard team, thank you in advance for solving this issue and plenty of kisses for you :heart:
