Rank condition error at initial steady state

Dear professor jpfeifer:
When i run my dynare to construct a transition path, at the initial value of the shock, it always notes that “The rank condition ISN’T verified!”. While the rank condition is verified at the endval value of the shock. I don’t know why there is such a big defference.

I would appreciate it if you could help me. Thank you!

Without context, it is impossible to tell. It seems that your initial steady state is special in some respects.
