DSGE ZLB and strange results

Occbin
1

Hello professor, I am doing a DSGE model and achieving a zero lower bound of interest rates using occbin, but when I analyze the results, a very strange problem arises. I put a negative capital shock on the model, but the capital is really increasing, I don’t know what the problem is, could you please help take a look

Are you sure your timing for capital is correct? It is contemporaneously chosen, implying that an increase in investment can counteract your shock.

I’m starting to rebuild the model, thank you, Professor. Best regards！
