Muli-instance parallel subprocess - dont work

Hello community,
I have a problem with process parralization. I have several companies. Each company has its own services. I want to parallelize the processing of companies, then at the level of each company, I want to parallelize the processing of services.
Below is my modeling and my yaml.poc_parallelisation_Or3.bpmn (5.2 KB)
I am using spring boot.
My config YAML is:
enabled: true
deployment-aware: false
core-pool-size: 3
max-pool-size: 30
queue-capacity: 10
keep-alive-seconds: 0
lock-time-in-millis: 300000
max-jobs-per-acquisition: 5
wait-time-in-millis: 5000
max-wait: 60000
backoff-time-in-millis: 0
max-backoff: 0
backoff-decrease-threshold: 100
wait-increase-factor: 2

it does not work, I only have sequential execution and not parallel execution.
Can anyone help me?
Thanks in advance.

You need to remove exclusive selection from Multi Instance Asynchronous options.
