Hey @alinash1
Let me reply to your queries one by one.
1. The image wasn’t displaying with {the custom field name} setting which was fixed in the latest release.
How are you managing the custom image field with custom coding or with ACF(Advanced Custom Fields)?
Here is what you need to do, The meta value of the image field you have created will go inside the Related Posts Thumbnails settings field. ( It can be the ACF field of image, a custom field of the image with coding )
2. The “Thumbnails Size” is 150×150. Currently, you have set it to 130×80.
