I have recently came across a Form library I have published where IP, when promoting the fields, converts the fields name to a GUID. making it a long string. Although in the list view and settings the display name is viewed normal, it's the Field Internal Name that is returning as the GUID. Makes it very difficult to read and confirm in formulas. This has only occured, to my knowledge, using IP 2010 and SP 2010 together. Does any one know why this is happening? Is there a way to fix or change this?
