I found the cause of this issue. It happened because of the unwanted
components that occupied the page while doing authoring. After removing
that unwanted components, it was working fine. Thanks everyone for the
support.
After downloading and installing the package from the git I am getting
this error - "HTTP ERROR 503 AuthenticationSupport service missing.
Cannot authenticate request.". I tried steps based on this discussion ->

nothing worked. Please help me to solve this issue.
I am working with AEM 6.2 local instance. Here the Configuration Browser
is missing. Can someone guide me on how to enable it so that I can
create Editable templates? I would really appreciate it if someone helps
me.
