Image Linked to Document cache

I have a document with a number of images, each stored elsewhere in the binder and added to the main document using “Image Linked to Document”. My problem is that this caches a long list of every image inserted, including old versions with the same name. How do I clear this “recently used files” cache ?. I would rather have none than a list of files I most likely never want to insert again ? It persists across closing and restarting Scrivener. See attached screenshot.

Are the images still in the project’s trash folder?

Emptying the trash should remove the items from the list.

Thank you. Yes, that got rid of the outdated duplicates.
