Removing OH1.1 binding

So I swapped over to the new modbus2 binding by using PaperUI I did remove all the old modbus.cfg files but it still gives me this error in the log. So how can I properly remove modbus1 binding, is there a jar file laying around somewhere?

Is the jar in your addons folder? IF so, stop OH, remove it ( I would just move it aside so you can revert) and look here.
