Oscillatory IRF

Hi professor, I got a IRF result with some oscillatory issues. I post here for you reference. I checked timing issues and model specification. Are these results reasonable? May I put it in my paper directly?

You don’t have typical oscillations arising from complex eigenvalues, but rather unusual dynamics for some shocks. Without knowing the model in detail, it’s impossible to tell whether what you show is wrong or simply consistent with the model.
