Importing Purchase Journals

SUGGESTED

I'm attempting to import a purchase journal, I've included the mandatory fields listed at  What are the Purchase Journal fields for Import / Export?

So these are the ones I have included:

Vendor ID,Date,Date Due,Accounts Payable Account,Number of Distributions,G/L Account,Quantity,Item ID,U/M ID,U/M No. of Stocking Units,Description,Unit Price,Amount,Recur Number,Recur Frequency

I had originally included this field as well: Invoice/CM #

However it kept getting stuck so I removed it from it completely in order to figure out what's wrong. It keeps asking for it even though I've removed it from the chosen fields when importing and it's not included in the .csv . It keeps getting stuck and stuck and now I can't even figure out what's wrong with it because it has no reason to keep getting stuck there. 

       

Any help would be appreciated.
