Archmage lvl 21 bug

Hello Everyone

When you get a lvl 21 archmage gem (20 + 1 corruption) dmg doesn't show in the tooltip (spark as example)

But if you use a lvl 20 archmage + lightning mastery to achieve lvl 21, the dmg really change

i'll drop an image about this




Please let me know anything or maybe i'm just dumb

Thanks to all
