Enquiry about IRF graphs

Dear all,
I estimated a dsge model and did not get any error message throughout the process. However, the graph for my IRF seems a bit strange and I would like to get any clarification whether something is wrong or not.

Without any context it is impossible to tell. What do you find suspicious? What does your picture even show? What is the shock? What are the variables displayed?
