Erroneous detailed hardware metrics in VTune Amplifier XE 2013

Hello,

I'm having problems with my analysis results in VTune. Whenever i do an analysis, hardware event-based metrics behave strangely. Their "aggregator" (e.g. Bad Speculation) seems to show correct values, but whenever i expand that, detailed metrics (e.g. Branch Mispredict, Machine Clears) always show zero (the blue bar is missing).

To illustrate, here is a C++ code snippet that should trigger loads of L1 cache misses:

/* ... */

/*kEvilOffset is 0x1000, accessing data with this offset should result in a large amount of L1D replacements (assuming a 32KB L1 data cache)*/

__declspec(noinline) void DoStuff() {
  for (size_t i = 0; i < kAllocSize - kEvilOffset; ++i)
  for (size_t j = i; j < kAllocSize; j += kEvilOffset) {
    data[i] *= 39;
  }
}

/* ... */

After running a "General Exploitation (Sandy Bridge / Ivy Bridge / Haswell)" analysis, the blue bar for "Back-End Bound" is very wide (which - by the way - should be correct, since cache misses are in that category), but when i expand that category, there are no blue bars at all for any of those events. I also attached two screenshots. Am i doing something wrong?

I'm compiling with Intel C++ 14.0, and using VTune Amplifier XE 2013 Update 15 (build 328102).
