Greetings,
I am attempting to upload to HS 18.1 and I'm get the following error: "Must enter all Lock Out dates to ADD Payroll Lock Out Rules (_f1)"
_f1 is not in the drop down list within the Upload Wizard but I do see it when I look at the names collection (see pic)

Can anyone shed any light on the this error or know of source at list upload errors and descriptions
Thanks in advance for any info/help.
