Remove Featured Image link not working

Is this a setting on a theme or plugin?

This is core WordPress for a blog post.

I don’t think core has the ability to set featured images as links – can you screenshot the area in the dashboard you’re referring to? I may have missed it

Is it also happening when you switch to the TwentyFifteen theme?

Oh I understand now

@borko, I can’t switch. This is in production, and it’s not happening with my local copy.

It’s strange that you have two Remove Featured Image links. I suppose that one is added by the theme (or a plugin). Did you update something (WP, theme or plugin)? Is your theme updated/compatible with the WP version you’re using?

I agree that it is strange. The one that is hidden works, but the visible one does not. Everything is up to date and compatible. I need to keep digging into this.
