Hi, we had a calendar enabled in a category and it was displayed without problems. Now we have created a subcategory and the calendar is gone. I have checked the settings, and the category is still selected to display the calendar. Is this a bug or am I missing something? (It’s a private forum and I can’t share a link.)
AI-generated summary
icaria36 reports that after creating a subcategory in their private forum, the previously visible calendar in a category has disappeared. They confirm that the category settings still indicate the calendar should be displayed. JammyDodger initially hopes for a spontaneous resolution, but icaria36 confirms the issue persists on Discourse version 3.2.1.
JammyDodger then offers to investigate by attempting to reproduce the problem and requests step-by-step instructions for the settings used. They also reference a potentially related older topic about events calendars becoming hidden when subcategories are hidden, suggesting this might be a similar issue.
Did this magically reappear? 
Mmm no(t yet?). Was this a known problem now fixed? We are on 3.2.1 ( 5abd8e9bb0 )
No, I’m afraid that was just roll-the-dice optimism. 
Let me see if I can repro. Have you got a step-by-step of your settings I can follow to see if my test site does a similar thing?
I’ve just seen this older one in Related Topics, if this could be the same issue? Events: If subcategories hidden, so is the events calendar
