Retrieved from anomaly

Hi there folks.
Im having issues where a reference I have changed from journal article to a book, will still include a website that it was retrieved from. It also states later in the text that it was ‘retreaved from’ but has no more information. Ive tried taking away the doi and URL fields as well as date retrieved fields, but this info just keeps coming back. Im working in google docs with the chrome extension.

Thanks in advance for any help.

Thanks for the details, @Aidan_Duncan. Could you share the link to the original website, so I can import the reference to my library and try reproducing the issue? Also please let me know which style you are using in Docs. Thanks in advance!
