Psyker bug kinetic barrage?

Yesterday I noticed something was kinda off with kinetc barrage. Sometimes I pre-charge my BB when I hear the sound-q of a disabler or special mob. When I pre-charged without kinetc barrage everything works fine, but when the kinetic barrage effect is activated and I pre-charge and lock on a Target it resets a bit of the charge.

Is that meant to be ? (maybe without it is overpowerd or is it a bug?)

In following Video I tested it out in the Meat Grinder

Looks like a bug.
I suggest you add a little bit of extra info and move it over to Bugs section (bug reports like to see certain additional info to make it easier to reproduce).
