When I upgrade for ex. Zaibas from Level 4 (151 attack) to Level 5 (170 Attack). it didn’t update the description (still 151 Attack). Though it will update once you have confirmed to upgrade it.
It should be updated so there will be no confusion when checking regarding the skill desciption.
Current skill level (level 4 attack 151 -> level 5 attack 170)
Upgrading the skill (level 5 attack 151 -> level 6 attack 170)
Confirming the skill (Level 5 attack 170 -> level 6 attack 189)
Thank ToS!
