No standard assignment defined for BP role category &1

What causes this issue?

The role category &V1& is assigned to at least one role. However, if
this role category is not assigned, the indicator <LS>Standard
Assignment BP Role -> BP Role Category</> is set.
Since a role category can be assigned to several roles, it is necessary
that only one assignment is given this standard indicator. The
standard assignment of a role category to a role ensures, for example
in the case of the check for the existence of a business partner role,
that the relevant role can be determined when the BAPI or
API is used to read data with the help of the role category.
