Occbin/Dynare 6: Could not normalize the model

I’ve been working in a OccBin implementation in Dynare 6, and an error keeps poping up.
"Could not normalize the dynamic model. Variable Y is not in the maximum cardinality matching. "

Even with this error I can simulate the model and get IRFs, however I’d like to understand more about this error and if/how it is affecting my estimation.

Thanks

You can ignore that message. It would be relevant if you were doing a block decomposition of the model. It’s irrelevant for stochastic simulations and OccBin.
