We have several next-gen projects in our Jira. I can create child issues in some of them, but not in one particular project. The button is just not there:

At first I thought I lack privileges to do so... but I am a member (and even an admin!) in that project, so this is clearly not an issue.
I tried to work around this - to create a task and "add a parent" to it. Sadly, that option offers me only epic parents. I would like to have the usual hierarchy of epic-story-task-(subtask) instead.
What other configuration did I miss? Or is the issue, possibly, elsewhere?
