Is the +1 Arrow don't work with Straffe Skill?

As the title say.. Is the +arrow don't work with Straffe?

From the animation, when DBM is not using straffe I can see the 3 arrows but everytime he/she is using straffe, it becomes 2 arrows.

I also tried, it using Sara but I can only see 2 arrows, not 3.
