RQM 2.0.1.1: How are populated te columns available in the Defect Queries?

Hello,
I'm using RQM 2.0.1.1. I have a question arround the queries.
These are the queries created from  "Defects" / "Go To Work Items" /"Create Query"
I would like to have a precise description of the some columns available in the list and how they are populated.
Or have you a documentation where these columns are descripted.
I don't find this in any documentations.

I tried several queries but I don't exactly how are populated the columns below:
