Hi everybody,
I found in this link http://community.powerbi.com/t5/Desktop/In-line-hierarchy-levels-for-drill-down-in-power-bi-desktop/td-p/33427
this "Seems like it is picking up all the text based fields when you see click records."
It doesn't make sense, but that's how it works, the "see records" include the fields that are already part of the visualization you're working on, plus the text based fields left on your table, so, I tested changing the datatype of one of my measure fields that I wanted to show into a text, and when I right-clicked for the "see records" option, now I could see the field I was testing with in the records.
Hope this helps! at least while it's fixed.
