How to fix this error?

You choose menu option Goto -> Material group material (or "Material
group material maintenance") to call material maintenance. Here, you
should maintain the material group reference material in as much detail
as possible. It represents not only a user-friendly input facility but
also a source of default material data for the whole material group.
If you entered new value-only materials, you also need to change the
respective material group materials and/or hierarchy materials,
particularly the respective (plant-dependent) tax classification.
