Revenant Sword leaves "ghosts" behind

As shown on the left, the Revenant Sword MTX is leaving behind "ghost" copies of itself.

I'm using Molten Strike with a one handed sword, and I have +1 strike targets mastery and use Multistrike Support. Revenant Sword is leaving these copies behind, presumably from the "ancestral call"-style added strike targets, but they could be my own swords when playing the slashing animation.

It is unknown if this additional rendering causes any performance impact, but I figured I would report it anyway.
