daredevil passive bug (either description or how power works)

Did a test of Daredevil's passive using Parker's enemy stun and Arachnid Agility. I expected DD passive to do damage to each enemy, but it only targeted the front enemy.

With two enemies left, I stunned the team with Parker's Blue. Total enemy HP was: 80686 

5 hits from Parker AAgility, with 2154 strike tiles out did total damage of: 43,898 
7982 damage (5828+2154) per hit.  Total damage is 39,910.

43,898 total damage minus Parker w/strike is 39,910. Difference is 3,988. Which is DD passive of 1834+2154. 

Based on Daredevil's passive description, I would have expected it to hit both enemies:
"When a Stunned enemy is damaged, Daredevil deals 1834 damage to that enemy."  

From the math it only hit one. Wouldn't you expect it to hit both enemies? Personally I read it as each damage should have done an additional 3,988 per Parker's hit. But at the very least, it should have done it twice (one per enemy)

I suspect this is a technical issue and it should hit all stunned enemies.
