Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
The Redirection Module and the Breadcrumb settings are probably missing because you have yet to activate the Advanced mode in Rank Math.
To do that, navigate to WordPress Dashboard > Rank Math > Dashboard. In the top-right corner, click on Advanced Mode as shown below:

Once you’ve enabled Advanced Mode, you can access all the available options in Rank Math. You can also notice that more modules will now be available for you to access in the Rank Math dashboard.
1) To enable the Redirection Module, Navigate to Rank Math > Dashboard and enable the Redirections module, as shown below.

2) You can activate the breadcrumbs setting in Rank Math from Rank Math > General Settings > Breadcrumbs.

Hope this helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
