Issues with replicating models with steadystate files

Dear MMDB team,

I am trying to replicate some of the models in your database. I noticed that generally I can not replicate the models with an external steady state file, in all the cases the same error messages appear:

Error using xxx_steadystate
Too many input arguments.
Error in evaluate_steady_state_file (line xx)
[ys,params1,check] = h_steadystate(ys_init, exo_ss,M,options);
Error in evaluate_steady_state (line xx)
[ys,params,info] = evaluate_steady_state_file(ys_init,exo_ss,M, options,steadystate_check_flag);
Error in steady_ (line xx)
[steady_state,params,info] = evaluate_steady_state(oo_.steady_state,M_,options_,oo_,~options_.steadystate.nocheck);
Error in steady (line xx)
[oo_.steady_state,M_.params,info] = steady_(M_,options_,oo_);
I assume the issue is that the model cods can not read the steadystate file. I am using

As I am going back to these models after 4 years, I assume there has been changes in the syntax for these files. I am currently using Dynare 5.1 version.

I would appreciate if you could give me an advice.

Many thanks in advance and best regards
