Running ADManager Plus 5040. Won't recognize ldap header msRTCSIP-OptionFlags

Running ADManager Plus 5040. Won't recognize ldap header msRTCSIP-OptionFlags

I have a CSV file that I use to import in changes to AD.  Works great.  Now I am trying to update the following fields for OCS 2007 R2 integration:

msRTCSIP-Line   (works great)
msRTCSIP-LineServer  (works great)
msRTCSIP-OptionFlags  (when I add this to my CSV file, the CSV file will not load in ADManager Plus). I receive "
Unknown Error occured. Please check the LDAP Attribute Names & their values in the CSV file. Click here to view the Sample CSV file.

I am doing this only for people that already have OCS enabled, just trying to add in these 3 additional fields

Anyone have any suggestions?
