Sub topic disappeared under the menu bar

[ShanChathusanda93]

Description:
When clicking to a sub topic in IS docs, we can navigate to the corresponding sub topic and the link is also changed and we can use that link to access it directly. When we click on a sub topic, that sub topic is disappeared under the menu bar[image_1] of the docs.

Ex : https://is.docs.wso2.com/en/5.9.0/learn/deploying-the-sample-app/#deploying-the-travelocity-webapp
When we try to load the travelocity webapp deploying subtopic, the Deploying the Travelocity webapp topic disappeared.
