Cannot create an instance of Oracle Java Cloud Service in Oracle Cloud

In Oracle Cloud when trying to create an instance of "Oracle Java Cloud Service", in Step 2, a database created in the same account does not show up, this not allowing me to create the instance.

Steps i'm doing:

1. Created a new compartment
2. Created a Oracle Autonomous Database Transaction Processing

 General Information
 Database Name: dbtr1
 Workload Type: Transaction Processing
 Compartment: surenk (root)/dbcompartment
 ...
 License Type: License included
 Database Version: 18c
 Auto Scaling: DisabledAuto Scaling
 Lifecycle State: Available
 Instance Type: Free

2. Then Platform Services > Java >

in Step 2, the above database does not show up in any compartments

What am i missing?
