Is there a limit to how many items you can render with an Ncurses menu?

Hi! I'm trying to render this list of 27 items:

  MENU *tasksMenu = renderMenuFromJson(tasksJson, "content");

  // Render
  projectWindow = newwin(row, col, 0, 0);
  projectPanel = new_panel(projectWindow);
  update_panels();
  post_menu(tasksMenu);
  refresh();

item_count(tasksMenu) outputs 27, so I know it's not an issue with the data that I'm using to create the menu. I know that:

If a menu has more menu items than can be displayed at once, only some of the menu items will be mapped onto the screen. (https://www.gnu.org/software/guile-ncurses/manual/html_node/Menu-Item-Procedures.html)
But the terminal that I'm opening is plenty big (row = 54, col = 107). What's going on here?
