You cannot do attachments to this list, I believe, so we can't see your model. Obviously, something is wrong. I can tell you that it is usually possible to set the covariance between the independent variables and the covariates to 0 but I bet it would mean a considerably worse fit unless somehow they are all independent of one another, which I doubt. Error terms are usually estimated.
