Hi,
Thanks a lot for your query and we are so sorry about the trouble this must have caused.
When you have more than 1 category on a post, Rank Math gives you the option to choose the primary category so that is the one which will appear in your Breadcrumbs:
Please check that setting and make changes to your articles as per your preference.
I hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
