I'm getting no response when clicking the "Add Rule" button under Field group settings → Location. This occurs on multiple browsers. It is only unresponsive on one Field Group. Older or newer field groups work as expected. Browser console shows no errors. /wp-json/mbb/include-exclude does not appear to be triggering upon click. Is this a known issue?
Using Meta Box AIO 3.0.1, WordPress 6.8.2, PHP 8.3.22.
I can provide access to a staging site if that is helpful. Thanks.
