i recently found out my car has a similar problem with similar parts. new adjustable beam, new CB dropped spindles, extra eccentric adjusters and the left side only adjusts to 0 camber. The right goes to -1.2 degrees. left has as similar range of movement as right, but only adjusts in +camber. i can only guess that the control arms (new) are bent on the left side. i've got a pair of new arms for the left on order from aircooled.net to see if that fixes it.
