SmoothedVariables equals observable Variables

Hi professor, I estimated the parameters and the result shows that SmoothedVariables exactly equal observations. Is that possible and what does it mean? This is the estimation command. The estimation takes almost 40 minutes. Please let me know if you need my mod files. Thank you very much for your help.

estimation(order=1,datafile='mydata.mat',posterior_graph,nobs=131,mh_replic=2000,mh_nblocks=2,mh_jscale=0.8,mode_compute=6,mode_check,smoother,consider_all_endogenous);
