Rapidweaver has detected missing resources

Rapidweaver has detected missing resources in this project

It appears that all my links are broken after I updated to the most recent version of RW Version (8.5.1 (20823)).In Advanced settings I have RW set to “Copy (Resouces) into the document” so why would they be missing?
File links are set as “Relative to page” which I believe is the default?
I looked thru the other answers to this question and none seems to resolve the issue. I know this is vague and I will try to give more info as best as I can since I’m still a newbie at RW.
