Disable LinkChecker for Adobe campaign newsletter does not work in 6.5

[Lavita]

We have disabled link checking and link rewriting in Day CQ Link Checker Transformer configuration. we have included this anchor tag in our page - <a x-cq-linkchecker="skip" href="#about-us">About Us</a> .

In adobe campaign we see - href="https://publish1.test.sites.cqms.netnull#about-us" publish domain getting added before actual url in href.

We have followed steps given in this link https://experienceleague.adobe.com/docs/experience-cloud-kcs/kbarticles/KA-16563.html?lang=en 

Can some help us here ?what is that we are missing in our configuration that it is still rewriting the href links? are there any specific steps we need to follow in author & publish instances ?

Note: We are on 6.5 SP10.

Can you check if there is sling mappings in place? You can check if any configuration is present on /etc/map/http or /etc/map/https. Link for your reference: https://blog.3sharecorp.com/shortening-urls-in-aem

If this does not help, check if you have disabled the service in the correct instance (author or publish) form where the URL is being referenced.
