Hello,
First of all, thank you for your purchase.
The plugin searches for featured images in this order:
1. From inside the feed
2. From the og:image meta tag of the article
3. From inside the post content
You can skip checking each step (depending on where the small images are located, in your case). So, to try to fix this, please go to importing rule settings, and check (one by one), the following checkboxes:
1. ‘Skip Checking Feed Image’ -> save settings -> check if small images are still imported
2. If not fixed, check also the ‘Skip Checking OG:Image Meta’ checkbox -> check if fixed
3. If not fixed, you can assign default feature images in the ‘Default Featured Image List’ settings field (this is the last case scenario).
Let me know if this helped.
Regards,
