Lots of false positives

Recently I'm getting a lot of false positives for my rules.
For example when adding a zip or ics file to my downloads folder, a rule that checks for pdf is triggered.
The logfile shows:
Could not retrieve metadata for file: <filename or foldername>
Hwre <filename or foldername> is the actual file or folder name. As can been seen from the above example, this file not just occurs with files, buut also with folders that are added to the downloads folder.
Hazel: 5.0.5
macOS: 11.2.1 (Big Sur)
This seems to have started fairly recently. Any idea what could be wrong? And even better, how to fix this?
