Multiple fields for scanning?

Hi, so this question is for a client of mine.

I set up the plugin on their site and it was working fine. For a custom post type, we needed it to scan the a “video” custom field, so entered it within the custom field option. However, they also need the plugin to work for the regular post post type and scan their blog posts for images. They are telling me that when “video” is selected in the custom field, the plugin no longer scans the blog posts.

Just wanted to touch base here before going into the process of troubleshooting.

Thanks
