Issues with NPC animations

[4amMadman 7]

So I'm building some new trade zones and have been playing around with the animations for traders. I keep encountering this issue where a trader will float or not intersect the object when the sit and lean animations are used. It seems that no matter how you position the npc they will float on initialization or (in the case of lean) move into position but be several feet out/away from the object they are meant to be near. I've tried disabling item simulation or making the item a simple object. I keep encountering this with lean, sit and sit high. I'm using 3den Enhanced if it makes any difference. Is there any way around this at all?
