This issue still exists. Anaplan will create an "empty" model then produce an error. You need to either remove formulas from the line items that are going to be used as DCA Read or Write drivers or clear READ and WRITE access drivers in module blueprint, this lets you create a model from a revision tag. Once you've created the model from the revision tag you can re-add the necessary formulas for the DCA driver line items or re select driver in blueprint, add a new revision tag and then sync the model successfully.
