As the title states: When you add a custom field and make it’s location to a ‘Taxonomy’…the field shows up twice when editing a term that belongs to said taxonomy. The issue was replicated with two different field types.
I cannot reproduce what you are seeing. The only way I know that this this can happen is that you have 2 field groups with the same fields that have different field group keys.
Here are some screen captures of the Custom Field page and an associated Taxonomy Term page to show the issue.
Also… I am using Extended and Pro.
Do you get the same result with ACF Extended deactivated? That plugin is by a different developer.
That might be the issue. When I disable the AC Extended it says the page I’m trying view has been deleted. That makes sense because I think ACF Extended is handling custom taxonomies… It’s a little disturbing because I thought it was the same developer…not a huge deal though.
If that plugin is controlling it then you’re going to have a hard time narrowing down the cause. The page you gave the sceenshot to does not look like my screen on a taxonomy so ACF extended is somehow adding this page. I would contact the developer of that plugin.
