Using lycanuim-Z in battle does not giveEXP or EVs

[Quasar47 1]

I don't know if the same bug happens for the other crystals-Z, but when I use a Lycanium-Z against any kind of wild Pokemon, the message "The wild X fainted!" appears correctly, but the message about the exp gained doesn't show up ; and when I check the stats of my Lycanroc, I can see that neither the exp nor the EVs have been updated.

 

EDIT : Justed tested with a Darkinium-Z and the same problem occurs. It happens when I defeat a wild Pokemon with a Z-move, but if it doesn't KO the enemy and I finish it with a regular move, I still get the exp and EV point.
