I am developing custom processor with hive database connection pooling service. Added necessary dependency in pom file and added necessary folders in custom processor folder. I have created class file and able to generate nar file. Placed nar file in lib directory and restarted nifi server. Its look like everything working fine. But services are not showing in database connection dropdown box. Instead it showing connection id, but every time services are creating when click "create" in controller section. For other processors, it seems working fine. Please find the attached screenshots.

Any help appreciated.
