License soft reject reason

This is the reason and I don’t understand it. I’m not including the demo images in the main download package.

> Assets used in item previews need to be properly licensed for commercial use. As the asset is not being resold or redistributed, you will not need a re-sale or re-distribution license as you would for use of that asset in the main file. However, you will still need a license for a commercial use (reproduction) for use within the preview. It’s important to read each license of any asset you’re intending to use carefully to make sure your use of the asset complies with the license terms.

Could it relate to something other than images e.g. Script, plugin etc?

Have you replaced all images with placeholders in the download copy?

No, I purchased all developer licences, it seems I used a few images that couldn’t be used in any way (not even in previews). Thank you for your answer!
