In the screenshot (https://prntscr.com/vpefz6), notice "Injured Bird" has a drop-down arrow next to it, although there are no submenu items.
mark-marylandraptorrescue-org Hi If you are using T4 Framework and in Navigation > Megamenu setting you turn on the submenu for injured bird menu item will display the dropdown. You can turn it off from the Megamenu options in template.
It is very wonky. I was finally able to fix it, but I have no idea what I changed that made the difference. It's not obvious, nor intuitive.
mark-marylandraptorrescue-org Make sure that you update the latest version for T4 plugin also, we fixed some issues in the latest one.
