Browserstack stopping session automatically


I’m not quite sure if this is the place to ask, but perhaps someone faced a similar issue.
I have a Browserstack Automate Pro trial subscription with 2 parallel tests.
I integrated browserstack into Katalon as described here but instead of making one remote execution, I made a few under “Custom”.
Whenever I execute a test, the session starts normally and everything works fine.
However, when the test completes, the session doesn’t stop automatically. Is this how it is supposed to work?
It is my plan to run the tests sequentially on all kinds of different browsers. However, when the session doesn’t stop automatically, it looks like browserstack thinks I’m running the tests parallel.
So my question is, is there some way to stop a session automatically without having to manually click on “stop session”?
Any help would be greatly appreciated.

So it was the checkbox under Project->Settings->Execution for “Terminate drivers after each Test Case” or “… Test Suite” dependent of when you wish the drivers to quit.
