I've noticed ACT attributing weird extra damage and extra hits to certain attacks and skills, and aside from possibly skewing the numbers incorrectly it's kind of confusing when reviewing the info.
ex.
Bootshines -> 31
True Strikes -> 32
Dragon Kicks -> 149 (34*)
Twin Snakes -> 66 (33*)
DK has a ton of extra 15 dmg hits attributed to it as if ACT thinks it's a DoT (but multiple values show up per second) and Twin Snakes has a bunch too (not as many).
edit: It does it with other stuff like Mudras and Wrath but it's generally pretty inconsequential and ignorable, in this case it kinda fucks with the numbers tho (at least when trying to review the parse).
