C# - some values retrieved from a SOAP web service are null when

I am retrieving values from a SOAP web service. It's weird, because almost all the values are there, but SOME of them (~5 out of 100) are null. I used Fiddler to verify that the SOAP message that's being sent to the c# client has these values present, but they're null when trying to access them from code. The values I'm trying to access are in an array. It correctly displays the number of elements in the array, but the values inside the array elements are null.

I am stumped. I searched for answers but could only find cases where ALL the values were null, and it was a namespace problem.

What could be the cause of this? Any help would be appreciated.
