Hazel 5 Can't see inside files anymore

Upgraded to 5. Running Catalina. Most of my rules vanished... oh well? It's going to be a pain and time intensive to recreate them all. Sigh. I suppose they are gone forever?
Rebuilt a rule. Did a preview. Says there is no match. I look at the PDF. Searchable item is there. Try four more. Nope.
Go to another rule that DID move over. Preview there. No match.
In fact, none of the existing rules that moved over to Hazel 5 match anything.
Tried a preview of a document that Hazel 4 DID match and has since renamed and sorted. No match.
It will only match items with Document Name. Nothing more. It's like it lost the ability to see inside documents.
What's going on and how do I fix it?
