Hi,
Could you confirm you are using the latest version of WordPress 5.6, Yoast SEO for WordPress 15.5, WooCommerce 4.8.0, and the latest versions of your plugins and themes?
Could you let us know how you are creating these product bundles? Could you let us know which specific plugin you are using?
We’re sorry that you are experiencing problems that might be caused by our plugin! Just to be sure, we would like to rule out any plugin or theme conflicts that may occur. The fastest way to do this is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Nineteen.
Test this on your development or staging site, if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin allows you to run a conflict check without affecting normal visitors to your site.
As we can imagine that you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts.
We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue.
