custom shortcode in bulk creator

Hi, I am trying to create a custom shotcode to give me the "next section" in order to create a transition in the main content prompt to the next title in line. For this I have created a shortcode like this: next_section => gpt-3.5-turbo-instruct @@ Look at the list %%sections%%, recognize which section you are in and enter the following section (heading). When I then run this task, it will fail. Does the custom shortcode not support nested shortcodes? Is there any other way to achieve this?
