That's enough tries to see it's V4, not the pants!  I've had something similiar happen to the Versas outfit by Renapd when I did a conversion of it!

Go to material room, click on the buttock/hip area of the converted out and see if it IS there, but INVISIBLE.  If so, turn the visibilty slider down to 0% and see it turns up. If so, turn it back up to full and see if it disapears again.
