RT 3.6.4 query issues

To all,

In testing the 3.6.4 release, I have come across a couple weird results 
  1. the sort seems (no, it DOES) ignore Custom Fields. I thought this was
    supposed to be a new feature from 3.6.1 on?

  2. When selecting the “load to spreadsheet” option with the results, I
    get a lot of extraneous fields (none I selected initially) loaded as well.

    Anyone have an answer for either of these issues?
