I'll guess you're using Solr 7.x and those fields in your schema were created automatically?
As of Solr 7.0, the schemaless mode field guessing added a copyField rule for any field that's guessed to be text to copy the first 256 characters to a multivalued string field. The way it works is a field is created with the type "text_general", and a copyField is then automatically created with the dynamic field rule "*_str" to create the multivalued string field. This came from https://issues.apache.org/jira/browse/SOLR-9526. You can prohibit the behavior if you want to by removing the copyField rule section. See the docs for where in the solrconfig.xml you will want to edit: https://lucene.apache.org/solr/guide/schemaless-mode.html#enable-field-class-guessing .
