Joint disappears when I execute "build" in Advanced Skeleton. (body)

[hqodh]

Hi guys, I have a problem with body rigging with Advanced Skeleton.

After positioning joints to my human character mesh, and doing "build", some of the foot joints disappear(heel, pinky toe, big toe joint). 

I wonder if anyone here that has the same problem as me and wanna solve the problem if possible. 

** I attached the reference mesh file.
