Perhaps the values that you need are calculated and Cant be retrive directly from DB. You could debug the standard program to check how those field are populated, perhaps there is some functions that you could use.
The other option, if you read the list from memory, you could parse that info and retrieve only the values that you need althought is not very elegant. The output that you get is separated with "|" ? then you could split string at "|" to see witch column number has the value that you need and then loop split and take the values that you need.
IMO debug the standard report and try to find out how the field is populated.
