Hazel constantly is running

Hi - I have all my content on my desktop in a deep folder structure... and I have the following rules to label and OCR all PDF's that I might have... however, Hazel does not stop running once it reaches the end of the folder structure it runs in a loop and I am not sure where do I have one - these are the rules that I have - can someone please help me figure out where I went wrong?
1.Rule 1
IF all conditions: Kind IS PDF; Tags DO NOT CONTAIN "Need to OCR"; passes shell script
Do the following: Add tags "Need to OCR"; Rename with pattern name replace text "-ocr" with " "
2. Rule 2
IF all conditions: Kind IS PDF; Name DOES NOT COTAIN "-OCR" passes shell script
Do the following: Rename with pattern name -OCR extension
3. Rule 3
IF all the conditions are met:Kind is PDF; tags contain "need to OCR"
Do the following: Run applescript; rename with pattern name "-OCR" extension; remove tags "Need to OCR"
4. Rule 4
IF all the conditions are met: Kind IS Folder
Do the following: Run Rules on Folder Contents
Thanks in advance!
