Motor6d acting extremely weird?

So, (mods please don't take this down my game is counting on this question being answered) me and my team were animating some sword attacks using a motor 6d. We already know we have to use instance.new to create a new motor6d through a script when using these, but when the animation plays, the sword just ends up in the air, nothing like what it looked like. We've tried editing the animation because maybe we accidentally messed with something related to position but even with that, the problem still persisted. My game has a big update which people are waiting for, but we can't release it with major animation problems, so can somebody please help? We've already tried solving it ourselves.
