I am planting milo with a FMX and Field IQ running a 1720 JD planter.  This set up worked well when I planted corn earlier, but after planting field borders it appears that the drives are not shutting off like they should when I plant into areas already planted.  I have 3 sectional hyd motors that run the planter, no individual row shut offs.  I have the right field entered and it is showing where I have planted already.  Any thoughts?  Thanks!
