Balancer can only replace another balancer without error if they have the same rotational alignment.
Because they are symmetrical, they should be allowed to replace themselves in any rotational alignment without error.
NB. This issue is mostly expressed when constructing blueprints that upgrade other blueprints. Other errors may be masked, and, if a balancer with updated settings has been accidentally flipped or rotated, it will not be replaced (i.e. updated with the new settings), which may cause the entire blueprint to malfunction.
