Dynare 6.2"Could not normalize the dynamic model."

Perfect foresight simulations
1

I’ve been working in Dynare 6.2, and an error keeps poping up.

Normalization failed with cutoff, trying symbolic normalization... 
Could not normalize the dynamic model. Variable I_k is not in the maximum cardinality matching.

But with this error I can simulate the model and get IRFs. and MODEL_DIAGNOSTICS: No obvious problems with this mod-file were detected.

When I run the mod file in Dynare 5.2, thers is no error message.

So what dost this error mean? I think the timing of capital is right.

The message is information related to the block decomposition of the model used in steady state finding or perfect foresight simulations. It typically does not point the user to actionable information. You can usually safely ignore the warning.
