Solr outputs the value of another field in one field

There is a project on Spring Boot and Solr. There is an Employee entity that has the Work Phone and MobilePhone fields. The data is stored in the Employee table, respectively, from PostgreSQL. When searching through a Solr worker, everything is displayed correctly, except for mobilePhone. The value from the workPhone is somehow passed to mobilePhone. Why?

mobile
