2 skill rapid fire causing rubber banding

Hello,

I started to use 2 different sets of rapid fire. 1 is focused on chaining and multiple targets, 1 is for single target high damage. Once I started using both and switching between the two I started to experience a weird glitch.

1 of the attacks starts to make my character "rubber band" and use mana and make no sound and shows no projectiles, but still does damage. Not fully sure what is going on there.

Character details + skills
Mercenary no ascendancy as of yet. lvl 28

Single target rapid shot (assigned to right click) - lvl 8 + ruthless + fire infusion
Multi target rapid shot(assigned to F) - lvl 8 + chain + envenom

small test, I can fix the issue by going back to town and re-entering the zone.

A bit of a late reply here but I am experiencing the exact same issue myself and it's really frustrating. I hope GGG sees this.
