Saltwater intrusion with OGS: In reading IC file, the input component names are not found in MCP file!

Hello OGS Users,
I am trying to reproduce a physical experiment on the effect of sea-level rise on lateral saltwater intrusion using OGS 5.8. It is more or less similar to Goswami-Clement problem. I am using almost the same setting and input files for the latter problem, but unfortunately, the model crashes and show this message
Error: In reading IC file, the input component names are not found in MCP file!!!
I am checking my IC file and MCP file and find that there is no problem as compared to the same setting used in the Goswami-Clement problem or Henery Problem.
Could you kindly guide me toward a solution to this problem?
Thanks in advance for your reply.
