Evading With The Dragon Nikana

[VicAnimus]

When I have the Dragon Nikana equipped and try to roll or evade the animation messes up at the end. The character will lean forward as if they are starting to run, then they are instantly standing up straight. This keeps me from moving for an extra second. When I try to do the jump and evade trick I lose all momentum at the end of the animation and plummet straight down. When I switch to other melee weapons the evade worked fine, though I'm not certain about the regular Nikana.
