Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
1. We removed other multiple Social meta options, as they are not required anymore for the Knowledge Graph by Google & Bing. You should only see the needed options in the Global Social Meta settings page. Currently the only options in Rank math are facebook and twitter. Here is a screenshot for your reference: https://i.rankmath.com/vc91MU
2. Are you referring to social sharing images and descriptions? Could you please share a URL we can check from our end or some screenshots to compare how it appeared previously and now? You can also check your URL using facebook debugger here: https://developers.facebook.com/tools/debug/ to confirm if the opengraph meta is added correctly.
