Upload HR11 with Excel Add-In

Hi All,

I already map all the fields in the excel based on the FORM. In my specific case the first 3 User Fields are requiered.

Issue that I am haviing is "User Field is required (_f490r0)". Of course is mapped, but keep saying this, so I not being able to create the employee because of this situation. Is some one can help please?  Weird thing is that i was trying (in production enviroment) to add an employee and I did it! but now it doesnt work anymore :(
