Since you mentioned it, I did some spot checks. I only just noticed that the files with names May 16 (released May 12) and May 23 (released May 19) and June 6 (released June 2) are also garbage. In addition to the one that you mention, the one named July 4 released June 29.
Can you confirm you're seeing the same?

All prices seem to be bad in all of those weeks, much like the errors last year but unlike the errors earlier this year that had the total return fields wrong.
The total return fields are wrong in (at least) the update files with these names:
Jan 10
Jan 17
Jan 24
Jan 31
Feb 2
Feb 14
Feb 21
Feb 28
Mar 7
Mar 14

The quick check for that TR problem is that either
* the Total Return 13-Week and 26-Week fields are both blank.
* the Total Return 13-Week and 26-Week and Year-to-Date fields are identical
