I updated an older Solr 4.10 core to Solr 7.1 recently. In so doing, I took an 
old 'gradeLevel_enum' field of type EnumField and made it an EnumFieldType, 
since the former has been deprecated. The old core was able to facet on 
gradeLevel_enum, but the new 7.1 core just returns no facet values whatsoever 
for that field. Both cores return gradeLevel_enum values ok when 
fl=gradeLevel_enum.

In the schema, gradeLevel_enum is defined dynamically:

<dynamicField name="*_enum" type="text_enum" indexed="true" stored="true" 
multiValued="true" />
<fieldType name="text_enum" class="solr.EnumFieldType" docValues="true" 
enumsConfig="enumsConfig.xml" enumName="gradeLevels"></fieldType>

This simple query fails to return any facet values in 7.1, but does facet in 
4.10:

http://localhost:8983/solr/core1/select?facet.field=gradeLevel_enum&facet=on&fl=id,gradeLevel_enum&q=*:*&wt=json

Thanks for any insight.
