I ended up just turning off the K-2 in Proseries and preparing them myself using the pdf forms on the IRS website.  Yes, it was a PIA.  But I couldn't figure out how to get rid of the error messages either in ProSeries.  Just a warning though, if you do it like I did, you will need to print the IRS forms in a lower definition. Otherwise the file will be too big to file electronically with ProSeries.  You will be able to attach them, but when you try to file it won't go.
