ETL and System Tables

Hello. I'm trying to acclimate myself to the Neo4j ETL Tool, using MSSQL in my JDBC connection. Although I'm specifying a specific source database, the ETL seems to pick up all the tables and schemas from the System Tables (master, model, msdb) on my server.

I thought I could work around this by specifying a specific schema in my connection, but it seems to pick up everything.

Any suggestions?
