Image Issue with AMP for WP

I have image issue with AMP for WP. I have been using premium template since 2019 and work well with AMP for WP until early 2020 this issue appear.

I am personal blogger by the way thus I have less technical skills on this matter. Have tried to read as many thread as possible on “double images” issue yet still not solving my issue.

Since then i quit the premium template and uninstall AMP for WP. The looks are great yet the traffic drop drastically. Then i decided to use available free template from wordpress and installed AMP for WP plugin again.

And here comes the issue again.

Following all possible threads related to image, here is my amp setting:

Change internal links to AMP = ON
Featured image from Custom Field = OFF
Featured image from Content = OFF
Duplicate featured image = OFF
Default fallback image = my domain/wp-content/plugins/accelerated-mobil-pages/images/SD-default-image.png

This issue appears on the homepage, related post and on contents. Here’s the problem looks like:
