May I know what happened to the scale of y-axis?

Dear all, may I have your help with the irf graphs ?
The scale of the y-axis apparently is wrong here, I appreciate it if you can explain to me what caused it ?
The value of steady state ? Or the linearization function is wrong ?

but my model gave this to me

I really appreciate it if someone could tell me what is going on, big thanks

Without the file it is impossible to tell.
