Subtasks from Reminders shows as separate tasks

I have a lot of tasks in Reminders (macOS, Catalina) with subtasks. In Reminders they are grouped under parent task.
In GoodTask (on macOS) they showed as separate tasks, without any grouping.
Is this correct?

Hi @Vsubb, thanks for the feedback.

Yes, that's correct. Subtasks info in Reminders app is not opened from Apple to use for 3rd party devs.

I'll keep an eye on it and will check when Apple opens it.
