We have noticed that there are couple of links (VNF and PNF Modeling Requirements & ONAP Management Requirements) are not showing up under below section.

https://docs.onap.org/en/latest/guides/onap-user/design/pre-onboarding/index.html#validate-xnf-package-vnf-pnf

Recently we have removed extra back quotes as described in DOC-634 and below is the merged gerrit request for the same.
https://gerrit.onap.org/r/c/doc/+/109057

Looks like there is something is missing for the appropriate links in the index.rst file. Please have a look and fix the issue. Attached the screenshot.
