order of the columns in the row-value need to be rearranged in order to match
the index, be sure to make affinity conversions before the rearranging of
columns so that the correct affinity is applied. Fix for the bug
reported by [forum:/forumpost/eab63506cf|forum post eab63506cf]. This
problem goes back almost nine years to [ddb5f0558c445699].
