What causes this issue?

Model allocation rules are used to generate allocation rules on the
basis of allocation categories. They are used to help you group
together plants and contain certain control data for the allocation
rules to be generated.
They also contain the value of the quota for the plants in a category.
This value is of the "ratio" quota category. If you want to define
fixed quantities for plants in an allocation rule, use a standard
allocation rule for the plant group or generate an allocation rule
using the plant quotas.
