AdSense ads not appearing in AMP Homepage

Hello,

I’ve got ads displaying on all AMP pages but not on the homepage.

If I go to https://gkmalayalam.com/amp there are no ads displaying but if I take any post from the homepage, you can see header ads appearing on the top of the page.

Let me know how to fix this?
