Archmage level 26 (from 9-10% Bug). No damage increase.

I reached the level 26 archmage breakpoint with the following bonuses: +1 from a support gem, +1 from corruption, +3 from Prism Diamond (Archmage +3), and +1 from amulet corruption (+1 to all skills).

Despite all of this, there's no change in damage/dps from the increase from 9 to 10% non-channeling spell damage.

I came across posts on the forums mentioning the same issue with Archmage damage not increasing from 8-9% and that this was fixed on Jan 9th patch, "Fixed a bug where the Corrupted Skill Gem Level Modifier wasn't applying."

My DPS on Spark for example remains: 125K despite going from 9-10%.

I apologize for the prior image link -- here is the updated link: https://imgur.com/a/wVR3ber showing 10% damage. It does not translate to increased DPS on my skills.

Just following up, as it’s been a while. Is there a way to test whether this is a tooltip reporting bug or if it’s actually not translating into an increase in damage?
