Hazel 6 Not Applying Rules Properly to Monitored Folder

I’ve been using Hazel 6 on macOS Ventura 13.2, and I’m experiencing an issue where rules are not being applied consistently to a monitored folder. The folder contains various file types, and while some rules work as expected, others fail to execute or only apply intermittently.
I set up a rule to move PDF files with a specific tag to another folder.
The rule condition is "If all conditions are met: Kind is PDF and Tag is 'Invoice'".
I added an action to move the file to a designated folder called Processed Invoices.
I dropped multiple files matching the criteria into the monitored folder.
Some files are moved as expected, while others remain in the monitored folder. Occasionally, the rule does not trigger until I restart Hazel or manually force the rule to run. No error messages appear, but the inconsistency is disrupting workflow.
Does anyone know why this might be happening or what else I can try? Is this a known bug with Hazel 6, or could it be an issue with macOS permissions? Any advice would be greatly appreciated!
