sometimes it works, sometimes not

Hello,
at this point already thank you for helping me.
I use Hazel for many years now. In the last few months Hazel has problems with pdfs. I didn't change the rules or s.th. else.
Sometimes Hazel recognizes the rules, sometimes not. Most problems occur with the content of PDFs. Hazel doesn't recognize the content. Rule example "Contents contain xxx": In Preview it shows "Rule does not match". If I click on the red cross, it shows me "xxx" in the content but Hazel can't recognize it.
I tried without success:
- I exported my rules, deleted the folder and imported everything.
- I renewed the rule
Maybe you know a solution.
Best regards,
Cal
