650 new holland round baler tying issue

I have a 650 nh baler and every 10 or so bales sometimes it'll trip like normal and tie the bale but when it gets to home position the arms will trip again and retie the bale. Sometimes it'll retie the bale 3 or 4 times till I shut her down. Then it may roll 5 or 6 with no issues. What could be causing this. Thanks for any help!
