No Teaser Template Available while creating Campaigns

Hi,

We have implemented personalization and now we were trying to create the teaser for the page. In mcmadmin screen, I create a Brand, then a campaign, then in campaign we create a teaser. Clicked on campaign and then clicked on "New", it showed me options for various templates available for use. I am not able to see any template to create a teaser. It is even shown in the article available at: https://docs.adobe.com/docs/en/aem/6-1/author/personalization/campaigns/teasers-and-strategies.html

but the teaser template is not available to me. Screen shot attached. Any ideas why I am not able to get the template?

Thanks
