Click on reference not working

In google doc, when I clicked on the references in the text, it used to show up a menu where I can directly edit the references. However, now it only shows a URL link (image below), which I can’t do much with it. Can anyone advice?

Thanks for reaching out here, @Hsin. This usually means the extension (or the browser) needs to be reloaded - check out this page from our Help Center for more details. Let us know if that doesn’t do the trick.
