Dual wielding animation problems

When I said "moves sluggishly", I did not mean her attack speed; I was talking about her running speed. When I made her target a mob while she was barehanded, she runs normally. When I switched her weapon set to dual wielding, she goes into the idle-pose-animation and inches forward very slowly. Changing her weapon set back to barehanded makes her run normally. Switching back to dual wielding, she resumes inching forward. She essentially can't "run" while dual wielding. Or anything else.
